Question

A rectangle is 9 ft long and 40 in. wide. What is its area in square feet?

Answer 1

Answer:

29.97 square feet

Step-by-step explanation:

Given

The length of rectangle = 9 ft

The width of rectangle = 40 in

We have to bring the length and width in same unit. As the area is required in square feet so we will convert width in feet

The width will be divided by 12 to be onverted into feet

So,

Width = 40/12 = 3.33 feet

Now

Area = Length * width

= 9 * 3.33

= 29.97 square feet ..

Answer 2

Answer:

Area of rectangle = 30 square feet

Step-by-step explanation:

We are given that a rectangle is 9 feet long and 40 inches wide and we are to find its area in square feet.

For this, we will covert the width of the rectangle to feet and then find the area.

We know that:

$\frac{1 foot}{x} =\frac{12 inches}{40}\\x=3.3 feet$

So width in feet is 3.3 feet.

Area of rectangle = $9 \times 3.33$ = 30 square feet
