a trapezoid an area of 7.2 square miles.one base is 1.2 miles and the other is 2.4 miles long.what is the height

Respuesta :

Formula for a trapezoid is:

A = ((a + b) / 2) h

A is area, a and b are the base sizes, h is height.

Plug n' chug:

7.2 = ((1.2 + 2.4) / 2) h

Simplify:

7.2 = 1.8h

Divide both sides by 1.8 to get h alone

4 = h
