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: Find actual length

Since the scale is 1 inch : 5 feet and the length on - drawing is 8 inches, the actual length $L$ is $L = 8\times5=40$ feet.

Step2: Find actual width

Since the width on - drawing is 6 inches, the actual width $W$ is $W = 6\times5 = 30$ feet.

Step3: Calculate actual area

The area of a rectangle $A$ is given by $A = L\times W$. Substituting $L = 40$ feet and $W = 30$ feet, we get $A=40\times30 = 1200$ square feet.

Answer:

1200
