Assign the symbol L to the operand representing the length of the rectangle. For example, if the rectangle is 10 centimeters long and 5 centimeters wide, then L represents 10 centimeters.
Assign the symbol W to the operand representing the width of the rectangle. For example, if the rectangle is 10 centimeters long and 5 centimeters wide, then W represents 5 centimeters.
Write the operator that yields the rectangular area. Use the expression L x W as the rectangle area operator. The area of a rectangle is found by multiplying the length and width of the rectangle. For example, if the area operator (L x W) is applied to a rectangle that is 10 centimeters long and 5 centimeters wide, the operation yields a result of area = 50 cm^2 = 10 cm x 5 cm = L x W.
