Question

Using the picture below find the area of the trapezoid ?

Answer 1

Answer:

(a) 8x-16 $cm^2$

Step-by-step explanation:

From the given figure of trapezoid:

Height, h=8 cm

Bases, $b_1=(x-6)cm \; and \; b_2=(x+2)cm$.

Area of the trapezoid,

$A=\frac 1 2 h (b_1 + b_2) \\\\=\frac 1` 2 \times 8 ( x-6+x+2) \\\\=4(2x-4)$

$=8x-16 cm^2$

Hence, option (a) is correct.
