Question

q 1.) solve using the appropriate formula. hint: trapezoid: $a=\frac{1}{2}(b + b)h$ find the area of a trapezoid with b = 5 in., b = 3 in. and h = 2 in.

Explanation:

Step1: Substitute values into formula

$A=\frac{1}{2}(B + b)h$, substituting $B = 5$, $b = 3$ and $h=2$ gives $A=\frac{1}{2}(5 + 3)\times2$.

Step2: Calculate sum inside parentheses

First, calculate $5+3 = 8$. So the expression becomes $A=\frac{1}{2}\times8\times2$.

Step3: Perform multiplications

$\frac{1}{2}\times8 = 4$, and $4\times2=8$.

Answer:

$8$ in²
