# Area of Rectangle Formula

## Formula

The formula to calculate the area of a rectangle is:

Area = Length x Width

In this formula:

represents the total surface area of the rectangle.**"Area"**is the length of one of the rectangle's sides (typically the longer side).**"Length"**is the width of the rectangle, which is the length of the other side (typically the shorter side).**"Width"**

Simply multiply the length and width together to find the area of the rectangle in square units (e.g., square meters, square inches, etc.).

## Rectangle Questions and Solutions

**Question 1:**

Rectangle A has a length of 10 units and a width of 5 units. Calculate its area.

**Solution 1:**

To find the area of Rectangle A, we can use the formula:

*Area = Length x Width*

*Area = 10 units x 5 units*

*Area = 50 square units*

**Question 2:**

Rectangle B has a length of 8 inches and a width of 4 inches. What is its perimeter?

**Solution 2:**

To find the perimeter of Rectangle B, we can use the formula:

*Perimeter = 2 x (Length + Width)*

*Perimeter = 2 x (8 inches + 4 inches)*

*Perimeter = 2 x 12 inches*

*Perimeter = 24 inches*

**Question 3:**

Rectangle C has a length of 15 meters and a width of 6 meters. Find its diagonal length.

**Solution 3:**

To find the diagonal length of Rectangle C, we can use the Pythagorean theorem since the diagonal forms a right triangle with the length and width:

*Diagonal^2 = Length^2 + Width^2*

*Diagonal^2 = (15 meters)^2 + (6 meters)^2*

*Diagonal^2 = 225 square meters + 36 square meters*

*Diagonal^2 = 261 square meters*

*Diagonal = √261 meters (approximately 16.12 meters)*
