A figure is decomposed into 2 trapezoids. Both trapezoids have a base of 20 centimeters, height of 7 centimeters, and top side length of 16 centimeters.
Find the area of the composite figure.
126 cm2
140 cm2
252 cm2
280 cm2

Answer 1

252 cm²

Explanation:

2[½ × (20 + 16) × 7]

36 × 7

252

Answer 2

252
`cm^(2)`

Explanation:

To find the area of a trapezoid, you must add both the bases up then divide by two. After that you must multiply that by the height.

`(a+b)/(2) h` here is the formula where a and b are the bases.

`(20+16)/(2) * 7`

Simplify.

`(36)/(2) * 7\\\\18*7\\= 126`

That is the area of one trapezoid and since there are two of the same trapezoids, you must multiply by two.

`126 * 2 = 252`

Therefore your answer is 252 cm^2.
