Question

On a 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?
A right trapezoid is shown with height labeled 5 feet and one of the bases labeled as 9 feet, and the other base is labeled as 7 feet.

Answer 1

The area of the given right trapezoid ​is 40 ft².

What is the area of the trapezium?

Area of the trapezium = ½(a + b) × h

Given;

base 1 = 9 feet

base 2 = 7 feet

Height h = 5 feet

Area of the trapezium = ½(a + b) × h

Area = (9 + 7) x 5/2

Area = 16 x 5/2

Area = 8 x 5

Area = 40 Square feet.

Hence, the area of the given trapezium ​is 40 ft².
