Question

On the road, a bike sign in the shape of an isosceles trapezoid is to be painted. The sign and its dimensions are shown below. What is the area of the sign?

11 square feet
15 square feet
18 square feet
24 square feet

Answer 1

Equation

A = (b1 + b2)*h /2

Givens

b1 = 5 feet

b2 = 7 feet

h = 3 feet

Sub and solve

Area = (5 + 7)*3/2

Area = 12*3/2

Area = 36/2

Area = 18 Square feet.
