Question

Carmen’s living room floor has the shape and dimensions shown in this diagram. What is the area of Carmen’s living room floor?

Answer 1

Separate into two rectangles then add the areas of the rectangles

Answer 2

The area of Carmen’s living room floor is 300 square feet

To determine the area of Carmen’s living room floor, we need to know that the formula for calculating the area of a rectangle is expressed as;

A = lw

Such that;

• A is the area
• l is the length
• w is the width

Now, we have to determine the area of the rectangle that was cut out

Area = 8 (6)

Multiply the values

Area = 48 square feet

Now, we have;

Area = 12 (21)

Multiply the values, we have;

Area = 252 square feet

Area of the living room floor would be;

= 252 + 48

= 300 square feet
