Question

A rectangle has a length of 4 millimeters and an area of square 116 millimeters. What is the​ width? What is the​ perimeter?

Answer 1

• Width = 29mm
• Perimeter = 66mm

Explanation:

The area of a rectangle can be calculated by the formula:

= Length * Width

As we have the length and the area, we can make the width the subject of the formula to solve for it:

116 = 4 * width

Width = 116/4

= 29 mm

Perimeter is:

= Length + Length + Width + Width

= 4 + 4 + 29 + 29

= 66 mm
