A table has a length of 4 1/2 feet and width of 2 1/4 feet. Find the area of the table in square feet. (1 point)
Responses:
13 1/2
8 1/8
6 3/4
10 1/8
10 1/8
To find the area of the table, you multiply the length and width.
Length = 4 1/2 feet = 9/2 feet = 4.5 feet
Width = 2 1/4 feet = 9/4 feet = 2.25 feet
Area = Length x Width
Area = 4.5 feet x 2.25 feet
Area = 10.125 square feet = 10 1/8 square feet
So, the area of the table in square feet is 10 1/8.
Byron calculated the area of the rectangle as 22 square centimeters. What is the error in his reasoning and what is the correct answer? (1 point) Responses:
Byron found the perimeter of the rectangle. The correct area is 11 square centimeters.
Byron found the perimeter of the rectangle. The correct area is 24 1/4 square centimeters.
Byron found the perimeter of the rectangle. The correct area is 29 1/4 square centimeters.* MY ANSWER
Byron found the perimeter of the rectangle. The correct area is 22 square centimeters.
Byron found the perimeter of the rectangle. The correct area is 29 1/4 square centimeters.
If Byron calculated the area as 22 square centimeters, he probably found the perimeter instead. The error in his reasoning is that he incorrectly calculated the area. The correct area of the rectangle is 29 1/4 square centimeters.
Find the area of the rectangle LMNO, with vertices L(−5,7),M(−1,7), N(−1,−3), and O(−5,−3).(1 point)
Responses:
8 units by the power of 2
28 units by the power of 2
40 units by the power of 2
100 units by the power of 2
To find the area of the rectangle LMNO, we can use the formula for the area of a rectangle which is length x width.
To find the length, we calculate the distance between points L and M, which is 4 units.
To find the width, we calculate the distance between points L and O, which is 10 units.
Area = length x width
Area = 4 units x 10 units
Area = 40 square units
Therefore, the area of the rectangle LMNO is 40 units by the power of 2.
So, the correct response is:
40 units by the power of 2
u sure???????!
Apologies for the confusion in my previous response. Let's recalculate the area of the rectangle LMNO using the coordinates provided for the vertices L(−5,7), M(−1,7), N(−1,−3), and O(−5,−3).
First, we find the length of the rectangle by calculating the distance between points L(−5,7) and M(−1,7):
Length = 4 units
Then, we find the width of the rectangle by calculating the distance between points L(−5,7) and O(−5,−3):
Width = 10 units
Now, we can calculate the area of the rectangle:
Area = Length x Width
Area = 4 units x 10 units
Area = 40 square units
Therefore, after recalculating, the correct area of the rectangle LMNO is 40 square units.
So, the correct response is:
40 units by the power of 2.
Rani needs to buy sod to cover his new backyard. His landscape design is graphed, and the yard has corners at (2,20), (12,20), (12,5), and (2,5). Solve for the area of his yard. (1 point) Responses:
60 sq. ft.
46 sq. ft.
80 sq. ft.
150 sq. ft. MY ANSWER IS IT CORECCT????????
To find the area of Rani's backyard, we can calculate the distance between points (2,20) and (12,20) to find the length, and between points (2,20) and (2,5) to find the width.
Length:
Distance between (2,20) and (12,20):
12 - 2 = 10 feet
Width:
Distance between (2,20) and (2,5):
20 - 5 = 15 feet
Area = Length x Width
Area = 10 feet x 15 feet
Area = 150 square feet
Therefore, the area of Rani's yard is 150 sq. ft. Based on the calculations, your answer is correct.
So, the response "150 sq. ft." is correct.
