Question

q 2) solve using the appropriate formula. hint: trapezoid. a = ½(b + b)h. find the area of a trapezoid with b = 4 in., b = 2 in. and h = 3 in.

Explanation:

Step1: Identify values

$B = 4$ in., $b = 2$ in., $h = 3$ in.

Step2: Substitute into formula

$A=\frac{1}{2}(B + b)h=\frac{1}{2}(4 + 2)\times3$

Step3: Calculate sum in parentheses

$\frac{1}{2}(4 + 2)\times3=\frac{1}{2}\times6\times3$

Step4: Perform multiplications

$\frac{1}{2}\times6\times3 = 9$ in²

Answer:

9 in²
