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?
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. = \(\frac{5}{7}\) in.
So, 21 feet = \(21 \times \frac{5}{7}\) in.
21 feet = 15 inches
Now 28 feet = \(28 \times \frac{5}{7}\) 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.
