Question

1. brian wants to re - tile his bathroom floor. he does not need to tile underneath the bathtub. according to the drawing below, what is the area of the bathroom floor that needs to be retiled? 52 sq ft 60 sq ft 12 sq ft 38 sq ft

Explanation:

Step1: Calculate the area of the whole bathroom

The formula for the area of a rectangle is \(A = length\times width\). The length of the bathroom is \(8\) ft and the width is \(6\) ft. So, \(A_{total}=8\times6 = 48\) sq ft.

Step2: Calculate the area of the bathtub area

The bathtub area has a length of \(5\) ft and a width of \(2\) ft. Using the area formula \(A = length\times width\), we get \(A_{bathtub}=5\times2=10\) sq ft.

Step3: Calculate the area to be re - tiled

Subtract the area of the bathtub from the total area of the bathroom. \(A = A_{total}-A_{bathtub}\). So, \(A = 48 - 10=38\) sq ft.

Answer:

38 sq ft
