Question

ABCD is a trapezoid AB equals 1 cm and CD equals 5 cm in the area equals 7.5 what is the altitude of a trapezoid

Answer 1

Answer: 2.5 cm

Explanation:

ab=1cm and cd= 5 cm and the area= 7.5cm

Answer 2

Here we have to use the formula of area of trapezoid, which is

`Area = (b_(1)+b_(2) )/(2)*h`

Where b1 and b2 are the two bases and h is the height or the altitude .

It is given that, Area =7.5 , b1 =1 , b2=5, and h is unknown .

`7.5 = (1+5)/(2)*h`

`7.5 = 3h => h =2.5`

Correct option is the second option .
