question

Which figure has a greater area?

8 yd

5 yd

10 yd

key idea

Area of a rectangle:

Area = base × height

Area of a triangle:

Area =

× base × height

solution

First, find the area of the rectangle.

Find the base and height of the rectangle.

base:	8 yd
height:	5 yd

Use these numbers in the formula.

Area	= base × height
	= 8 × 5
	= 40

The area of the rectangle is 40 square yards.

Now find the area of the triangle.

Find the base and height of the triangle.

base:	10 yd
height:	10 yd

Use these numbers in the formula.

Area

× base × height

× 10 × 10

= 50

The area of the triangle is 50 square yards.
The area of the triangle is greater.
