Question

frank made a scale drawing of his house. the scale he used is 1 inch : 5 feet. his drawing is a rectangle 8 inches long and 6 inches wide. what is the actual area of franks house? square feet

Explanation:

Step1: Calculate actual length

Since 1 inch represents 5 feet and the drawing - length is 8 inches, the actual length $l = 8\times5=40$ feet.

Step2: Calculate actual width

Since 1 inch represents 5 feet and the drawing - width is 6 inches, the actual width $w = 6\times5 = 30$ feet.

Step3: Calculate actual area

The area of a rectangle is $A=l\times w$. Substitute $l = 40$ feet and $w = 30$ feet into the formula, so $A=40\times30 = 1200$ square feet.

Answer:

1200
