Answer:

4 in.

Explanation:

The area of a trapezium is calculated using the formula:


Area=(1)/(2)(Sum\:of\:the\:bases)* height

The given tra-pezoid has area
48 square inches.

The bases are given as 9 inches and 15 inches.

We plug in the known values into the formula to get;


48=(1)/(2)(9+15)* height


48=(1)/(2)(24)* height


48=12* height

Divide both sides by 12.


(48)/(12)=height


4 in.=height

Therefore the height of the trapezoid is 2 inches.

Answer:

Option D 4 inches is correct.

Explanation:

Area of trapezoid = 48 square inches

Base a = 9

Base b = 15

We need to find the height h.

The formula for area of trapezoid is

Area = (a+b)/2 * h

Putting the values, we get

48 = ( 9+15)/2 * h

48 = (24)/2 * h

48 = 12 *h

=> h = 48/12

h = 4 inches

So, Option D 4 inches is correct.
