Question

Find the required measurements of the following trapezoids. b1 = 12 cm b2 = 16 cm h = 9 cm. Compute the area. ? cm2

Answer 1

Area= (b1+b2)/h
= (12+16)/9
= 28/9 = 3.111

Answer 2

`126\text{ cm}^2`

Step-by-step explanation:

Since we know that the area of trapezoid is one-half the sum of parallel sides times height of trapezoid.

`\text{Area of trapezoid}=(1)/(2)*\text{The sum of length of parallel sides *Height}`

`\text{Area of trapezoid}=(1)/(2)*(b_1+b_2)*h`

`\text{Area of trapezoid}=(1)/(2)*(12+16)*9`

`\text{Area of trapezoid}=(1)/(2)*(28)*9`

`\text{Area of trapezoid}=14*9`

`\text{Area of trapezoid}=126`

Therefore, the area of our given trapezoid will be 126 square cm.
