Question

in a scale drawing of an apartment 1 centimeter represents to 2 3/4 ft if the length of the kitchen is 4 1/2 centimeters on a scale drawing what is the actual length in feet of the kitchen

Answer 1

To find the actual length of the kitchen you will use the understanding of ratios.

If 1 cm equals 2 3/4 ft, you would multiply 4 1/2 by 2 3/4. This is because you wil have 4 1/2 groups of 2 3/4.

4 1/2 x 2 3/4
9/2 x 11/4 = 99/8
99/8 = 12 3/8 feet

The kitchen is 12 3/8 feet.
