- solve some word problems that involve the area and perimeter of rectangles.

**How to find the area of a rectangle?**

The area of a rectangle is the amount of space it covers. It can be calculated by multiplying its length and width.

If the length of the rectangle is denoted by “l” and the width by “w”, then the formula for the area (A) is:

A = l x w

Therefore, to find the area of a rectangle, we need to know its length and width and then apply the above formula to calculate it.

**How to find the perimeter of a rectangle?**

The perimeter of a rectangle can be calculated by adding the lengths of all four sides of the rectangle.

If the length of the rectangle is denoted by “l” and the width by “w”, then the formula for the perimeter (P) is:

P = 2l + 2w

Alternatively, we can also express this as:

P = 2(l + w)

Therefore, to find the perimeter of a rectangle, we need to know its length and width and then apply the above formula to calculate it.

Have a look at these videos if you need to review how to calculate the area and perimeter of rectangles.
