Question

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

Answer 1

72 square inches.

Start by finding the dimensions of the scale drawing. If 36 divided by a number equals 9, then that number is 4. 36 / 4 = 9

So, you need to divide 32 by 4 as well to get 8.

This means the scale drawing is 9 inches long and 8 inches wide.

Finally, to find the area, multiply the length and width together. 9 * 8 = 72

The area of the scale drawing is 72 square inches.
