The length of a rectangle is four times its width.

The rectangle has an area of 1024 cm².

Work out the width of the rectangle.

Width of the rectangle is 16 cm

Step-by-step explanation:

Step 1: Let the width of the rectangle be x. Then length = 4x. Find width.

Area of the rectangle = length * width

⇒ 1024 = x * 4x

⇒ 4x² = 1024

⇒ x² = 1024/4 = 256

⇒ x = √256 = 16
