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

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

$Area = \frac{b_{1}+b_{2} }{2}*h$

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 .

$7.5 = \frac{1+5}{2}*h$

$7.5 = 3h => h =2.5$

Correct option is the second option .

Answer 2

Answer: 2.5 cm

Step-by-step explanation:

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