# What is the square feet of this shape?

I got 9192 but it’s not right Relevance
• 119*112=13,328

47*88=4,136

13,328-4136=9192sqin

• A = LW - lw

A = (112)(119) - (88)(47)

A = 13328 - 4136

A = 9192 in^2

Now convert it to ft^2

= 9192 in^2 x ( ft/12in)^2 =63.833 ft^2 answer//

For the working enlarge the figure. You will find all the steps there. • The only calculation required is - Find area of the bigger rectangle and subtract Area of the shaded rectangle from the one you got earlier. You get the Answer. For all the calculations, enlarge (open) the figure above.

• The area required=119*112-88*47=9192 in^2=9192/144=

63.8333333...=63 5/6 ft^2.

• The area of this shape:

(119*112 - 88*47) in^2

= 9192 in^2

= 9192/144 ft^2

= 63.83333333... ft^2

• I you join the base, you have a large rectangle with a small one on its base.

Area of large rectangle = 112 x 119 = 13328 in²

Area of small rectangle = 88 x 47 = 4136 in²

Area of shape = 13328 - 4136 = 9192 in²

to convert to square feet, divide by 144

9192/144 = 63.83 ft²

• The area of this shape :

(119*112 - 88*47) in^2 = 9192 in^2

= 63.8333333333333333... ft^2

• Area of large rectangle = (36 + 47 + 36) (112) = 13328 sq in

Area of small rectangle = (47) (88) = 4136 sq in

Area of shape = 13328 - 4136 = 9192 sq in

Convert sq in to sq ft

9192/ 144 = 63.83 sq ft.

• { shortcut (so less chance of arithmetic error) large rectangle = 119*112. } // regards

• We have two 112 inches by 36 inches rectangles and one 47 inches by 24 inches rectangle. So the area in square inches is

A = (112)(36)(2) + 47(24) = 8064 + 1128 = 9192 square inches

If you want the area to be in square feet, convert all dimensions to feet then get the area or convert 9192 square inches to square feet

But you are looking for area in square feet. We know that 1 foot = 12 inches, so

A = 9192 square inches x (1 feet/12 inches)^2 = 383/6 = 63.83 square feet

• I believe that is in square *inches*.

Calculate the big rectangle (112 x 119 = 13328)

Then calculate the smaller rectangle that is cut out (88 x 47 = 4136)

Subtract:

13328 - 4136 = 9192 square inches

But they want the answer in square *feet*.

Remember a square foot is 1 ft x 1 ft.

= 12 inches x 12 inches

= 144 square inches

So divide by 144 square inches per 1 sq. ft.

9192 sq. in. / 144 sq. in/sq. ft

= 63 5/6 sq. ft

(or 63.83333...)

• Ohh I see. Thank you so much!!
