Question

Pls HURRY 12 Points!!!

what is the area of this trapezoid?



A:96 in²

B:132 in²

C:168 in²

D:1344 in²

Answer 1

B

Explanation:

The area (A) of a trapezoid is calculated using the formula

A =
`(1)/(2)` h (a + b)

where h is the perpendicular height and a, b the parallel bases.

here h = 12, a = AB = 8 and b = DC = 3+ 8 + 3 = 14

A =
`(1)/(2)` × 12 × (8 + 14) = 6 × 22 = 132 in² → B

Answer 2

(B) 132 in²

Explanation:

Top Length = 3 + 8 + 3 = 14 in

Bottom Length = 8 in

Area of the trapezoid

= 1/2 (14 + 8) x 12

= 1/2 (22) (12)

= 132 in²
