Which figure has a greater area?

7 in

5 in

10 in

key idea

Area of a square:

Area = side × side

Area of a rectangle:

Area = base × height

solution

First, find the area of the square.

Find the side length of the square.

side:

7 in

Use this number in the formula.

Area	= side × side
	= 7 × 7
	= 49

The area of the square is 49 square inches.

Now find the area of the rectangle.

Find the base and height of the rectangle.

base:	5 in
height:	10 in

Use these numbers in the formula.

Area	= base × height
	= 5 × 10
	= 50

The area of the rectangle is 50 square inches.
The area of the rectangle is greater.
