Question

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

Answer 1

Area = 7.2 square miles

Base = 1.2

Second base = 2.4

Area of Trapezium = (1/2)*(Sum of Bases)*height

7.2 =  (1/2)*(2.4 + 1.2)*h

7.2 = (1/2)*3.6*h

7.2 = 1.8h

1.8h = 7.2

h = 7.2/1.8 = 4

Height = 4 miles.
