Step-by-step explanation:
bc i know math. a liitle bit and like to help.
It’s C because it works and it should help you get it right
We know that
[scale]=1 in / 30 in
scale=measure in the drawing/measure in the actual
[measure in the actual]=measure in the drawing/scale
the measure in the drawing are
3 in x 4 in
so
for 3 in
measure in the drawing=3 in
[measure in the actual]=3/(1/30)-----> 3*30------> 90 in
for 4 in
measure in the drawing=4 in
[measure in the actual]=4/(1/30)-----> 4*30------> 120 in
the measure in the actual are
90 in x 120 in
1 ft----------> is equal to 12 in
x-------------> 90 in
x=90/12-----> 7.5 ft
1 ft----------> is equal to 12 in
x-------------> 120 in
x=120/12-----> 10 ft
the measure of a bedroom in feet are
7.5 ft x 10 ft
the area=7.5*10--------> 75 ft²
the answer is
<span>the area of the room is 75 ft</span>²
