first option

Step-by-step explanation:

Let's make the following conversion:

40 inches to feet (Knowing that 1 feet=12 inches):

The formula for calculate the are of  a rectangle is:

Where l is the lenght and w is the width.

Therefore, when you substitute values, you obtain the following result:

The correct answer is first option 30 ft²

Step-by-step explanation:

Formula:-

Area of rectangle = l x b

l - Length of rectangle

b - Breadth of rectangle

It is given that,A rectangle is 9 ft long and 40 in

To find the area

here l = 9 ft

b = 40 in = 40/12 ft

Area = l x b = 9 x (40/12) = 30 ft²

Area of rectangle =  30 ft²

The correct answer is first option  30 ft²
