The rectangular floor of a classroom is 36 feet and in length and 32 feet in width a scale drawing of the floor has a length of 9 inches what is the area in square inches of the floor and the scale drawing

Area of the floor of the classroom is 72 inch².

Step-by-step explanation:

We are given the dimensions of the rectangular floor as,

Length = 36 feet and Width = 32 feet

Since, the scale drawing have the length = 9 inches

This gives, the ratio of the actual length to the scale drawing length =

Thus, we have,

, where x is the width in the scale drawing.

So, on solving,

i.e. x= 8 inches

Since, Area of the rectangle= Length × Width

Thus, area of the rectangular floor = 9 × 8 = 72 inch².

Thus, the area of the floor of the classroom is 72 inch².
