Question

A yield sign in the shape of a triangle has a base length of 90 centimeters and a height of 80 centimeters.

What is the area in square centimeters?

a. 1,800
b. 3,600
c. 5,400
d. 7,200

Answer 1

The area of the yield sign is 3600 square centimeters.

Step-by-step explanation:

The formula for the area of a triangle is 1/2 × base × height. To find the area of the yield sign, substitute the given values into the formula:

Area = 1/2 × 90 cm × 80 cm

Simplify the expression:

Area = 1/2 × 7200 cm2

Area = 3600 cm2

Therefore, the area of the yield sign is 3600 square centimeters, so the correct answer is (b) 3600.
