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?

Sagot :

Ryan2id
5 in --------- 7 ft
x in  --------- 21 ft

x = (5 x 21)/7=15 in

Otherwise:

5 in ---------- 7 ft
x in  ---------- 28 ft

x = (5 x 28)/7 = 20 in

Dimentions of drawing is 15 x 20 in

Answer:

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. = [tex]\frac{5}{7}[/tex] in.

So, 21 feet = [tex]21 \times \frac{5}{7}[/tex] in.

21 feet = 15 inches

Now 28 feet = [tex]28 \times \frac{5}{7}[/tex] 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.
