Question

The area of a trapezoid is 864 cm2. It has a height of 24 cm, and the length

of one of its bases is 30 cm. What is the length of the other base?

Answer 1

Length of other base = 42 cm

Explanation:

h = 24 cm

One of its base a = 30 cm

`Area=864cm^(2)\\\\((a+b)*h)/(2)=864\\\\((30+b)*24)/(2)=864\\\\(30+b)*12=864\\\\30+b=(864)/(12)\\\\30+b=72`

b = 72 - 30

b = 42 cm
