You want to produce a scale drawing of your living room, which is 21 ft by 28 ft. if you use a scale of 5 in. = 7 ft, what will be the dimensions of your scale drawing?

15 in. by 20 in.

Step-by-step explanation:

Dimensions of living room :

Length = 21 feet

Width = 28 feet

Scale : 5 in. = 7 ft

So, 1 ft. = in.

So, 21 feet = in.

21 feet = 15 inches

Now 28 feet = in.

28 feet = 20 inches

So, the dimensions of the scale drawing = 15 in. by 20 in.

Hence the dimensions of the scale drawing is 15 in. by 20 in.
