Step-by-step explanation:

Area of a rectangle

The area of a rectangle of dimensions x, y is:

A=x.y

The diagram provided in the question is to a scale of 1 inch=16 ft.

We have provided a modified diagram where all the dimensions are also shown in ft.

The longer side of the shape is 4*16=64 ft

The smaller side of the shape is 3*16=48 ft

The bottom side of the store is 2 1/4*16=36 ft

The leftmost side of the store is 1 3/4*16=28 ft

We need to find the value of x and y.

The value of x is x=64 ft - 36 ft = 28 ft

The value of y is y=48 ft - 28 ft = 20 ft

The area of the whole rectangle of dimensions 48 ft and 64 ft is:

The area of the small blue rectangle is:

The area of the store is:

Rounding to the nearest 50 square feet:
