A quilt design uses parallelogram-shaped pieces that have a base measure of 6 inches and a height of 8 inches. If 15 pieces are used in the quilt, what is the total area of the parallelogram-shaped pieces in the quilt?
a 150 in.
b 360 in.
c 720 in.
d 1,440 in.
b 360 in.
To find the total area, we need to find the area of one parallelogram-shaped piece and then multiply by the number of pieces used in the quilt:
Area of one piece = base x height = 6 inches x 8 inches = 48 square inches
Total area = 48 square inches/piece x 15 pieces = 720 square inches
John is moving up to the attic and wants to paint one wall blue. The wall is a triangle with a base of 21 feet and a height of 8 feet. What is the area of the wall to be painted?
a 42 ft
b 62
c 29
d 84
a 42 ft
The formula for the area of a triangle is:
Area = (base x height) / 2
Plugging in the values given in the problem, we get:
Area = (21 feet x 8 feet) / 2
Area = 168 square feet / 2
Area = 84 square feet
However, we only want the area of the wall to be painted, which is one half of the triangle. So, we divide the result by 2:
Painted area = 84 square feet / 2
Painted area = 42 square feet
Find the circumference of the 2 cm circle. Use 3.14 for
