Question

How do you find the area of composite figures

Answer 1

Answer:

87.5 cm squared

Step-by-step explanation:

To find the area of the composite figure, split the figure into two regular shapes: a triangle and a rectangle.

Triangle: It has a height of 15 - 10 = 5 cm and a base of 7 cm. Find the area using the formula A = 1/2 *b*h = 1/2*5*7 = 17.5 cm squared.

Rectangle: It has a length of 10 and width of 7. Find the area using the formula A = l*w = 10*7 = 70 cm squared.

Together the area is 87.5 cm squared.
