Question

4. Find the area of the polygon

Select the appropriate response:

A) 1200 sq inches
B) 21 square inches
C) 360 sq inches
D) 180 sq inches

Answer 1

D) 180 sq inches

Explanation:

It's a trapezoid

Area = ½(sum of // sides) × height

= ½(10 + 20) × 12

= 180 in²

Answer 2

Add the top and bottom dimensions together, divide by 2 then multiply that by the height:

10 + 20 = 30

30/2 = 15

15 x 12 = 180

The area is 180 sq. Inches
