Question

Complete the parts in each step to find the area of each trapezoid?

Answer 1

The area of the trapezoid is 20 in².

Solution:

Given data:

Length of the bottom base = 7 in

Length of the top base = 3 in

Height of the trapezoid = 4 in

Step 1: Area of the trapezoid formula,

$A=\frac{b_{1}+b_{2}}{2} \times h$

Step 2: Substitute the given values in the formula.

$A=\frac{7+3}{2} \times 4$

Step 3: Add 7 and 3.

$A=\frac{10}{2} \times 4$

Step 4: Divide 10 by 2, we get

$A=5 \times 4$

Step 5: Multiply 5 by 4, we get

A = 20 in²

The area given in the picture is wrong.

The area of the trapezoid is 20 in².
