So, (6a - X)*5a = Y*(a^2) - 35a
<span>=> 6a*5a - X*5a = Y*(a^2) - 35a </span>
<span>=> 30(a^2) - X*5a = Y(a^2) - 35a
</span>30 = Y and
<span>X*5 = 35 or X = 7 </span>
Answer:
A=80 square feet.
Step-by-step explanation:
First, we find the area of the model. 6*4=24. Now, due to the ratio of 1:40, we know that every inch is actually forty inches. So, you do this:
24*40=960.
So, the area of the actual living room is 960 inches. Or 80 feet.
CubeSA=6 squares
SA=6s^2
SA=24
24=6s^2
divide 6
4=s^2
2=s
quadrupled means times 4
2*4=8
8=new side
sub back
SA=6(8^2)
SA=6(64)
new SA=384 cm^2
