Question A rectangular poster has a length of 72 centimeters and a width of 15 centimeters. The poster is reduced in size by 6 centimeters in length and 3 centimeters in width. What is the area of the new poster?(1 point) square centimeters
First, calculate the original area of the poster:
Area = length x width
Area = 72 cm x 15 cm
Area = 1080 square cm
Now, calculate the new dimensions of the poster:
New length = 72 cm - 6 cm = 66 cm
New width = 15 cm - 3 cm = 12 cm
Calculate the new area of the poster:
New area = new length x new width
New area = 66 cm x 12 cm
New area = 792 square cm
Therefore, the area of the new poster is 792 square centimeters.
A piece of paper is in the shape of a right triangle. The base is 4.25 inches and the height is 11 inches. What is the area of the right triangle in square inches? Do not round your answer.(1 point) square inches
The formula to calculate the area of a triangle is:
Area = 0.5 x base x height
Substitute the given values into the formula:
Area = 0.5 x 4.25 inches x 11 inches
Area = 0.5 x 46.75 square inches
Area = 23.375 square inches
Therefore, the area of the right triangle is 23.375 square inches.
What is the area of the non-right triangle? The base and height are found by counting the squares. (1 point) The area is square units.
To calculate the area of a triangle, you can use the formula:
Area = 0.5 x base x height
From the information provided, since we are counting squares for the base and height, we can count the total number of squares as shown:
Base = 4 squares
Height = 7 squares
Now, substitute the values into the formula:
Area = 0.5 x 4 x 7
Area = 0.5 x 28
Area = 14 square units
Therefore, the area of the non-right triangle is 14 square units.
What is the area of the quadrilateral? (1 point) in.2
To calculate the area of a quadrilateral, we need more information about the shape of the quadrilateral. The area of a quadrilateral can be calculated using different methods depending on the information provided such as the shape of the quadrilateral, the length of sides, diagonals, and angles.
If you can provide more specific information or measurements about the quadrilateral, I would be able to help you calculate the area.
What is the area of the polygon? (1 point) Responses 68 square units 68 square units 77 square units 77 square units 83 square units 83 square units 72 square units
To find the area of a polygon, you typically need the shape of the polygon, the lengths of the sides, and/or the measurements of the angles. Without this specific information, it is not possible to calculate the area of the polygon.
If you can provide more details or measurements of the polygon, I would be able to help you find the area.
