Question

100 points, put nonsense, get reported. Susan wants to build a floor to put at the bottom of her tree house. She made the scale drawing below using a scale of 2.5 in = 3 ft. Enter the length Susan must use for the floor.

Answer 1

• Scale is 2.5in

Total 2.5in pairs

`\\ \tt\hookrightarrow (11)/(2.5)`

`\\ \tt\hookrightarrow 4.4`

• Now it is equal to 3ft

So length=4.4(3)=13.2ft

Answer 2

Divide the length of the scale drawing by the scale (2.5) then multiply that by the scale feet (3)

11 inches / 2.5 = 4.4

4.4 x 3 = 13.2 feet

Answer: 13.2 feet
