If the area of a rectangle is 72 square units and the length is 9 units, what is the width?

Back

The width can be found using the formula for area: Area = length × width. So, width = Area / length = 72 / 9 = 8 units.

If the perimeter of a rectangle is 30 units and the length is 8 units, what is the width?

Back

Using the perimeter formula: P = 2l + 2w, we can rearrange to find width: w = (P/2) - l = (30/2) - 8 = 5 units.

What is the perimeter of a square with a side length of 10 units?

Back

Using the perimeter formula for a square: P = 4s, the perimeter is P = 4 × 10 = 40 units.
