Question

There is a park near Raphael’s home. To find its area, Raphael took the measurements shown. Select all the true statements about the area of the park.

(a)The park can be decomposed into two parallelograms.

(b)The formula A = bh can be used to find the area of each piece of the park.

(c)The park can be decomposed into a parallelogram, a triangle, and a trapezoid.

(d)The area of the park is 126 m2.

(e)The area of the park is 96 m2.

Answer 1

A, C, and D

Explanation:

If you split the shape right along the bottom of the first part, you get two parallelograms. If you split it like you split it the first time and then split it along the side of the bottom parallelogram you get a triangle, a parallelogram, and a trapezoid. Then, because the area of a parallelogram is A=bh, you can substitute the numbers in. 5*12=60 and 6*11=66. However, this is not all, remember to add the area together! 60+66=126 so D is also true.

Hope this helps!
