Answer:2.8 feet
Step-by-step explanation:
length(l)=?
breadth(b)= 1.9 feet
perimeter(p)=7.4 feet
we know,
p=2(l+b)
7.4=2(l+1.9)
7.4=2l+3.8
2l=7.4-3.8 (changing side and bringing 3.8 to 7.4 it gets -3.8)
l=3.6/2
l=2.8 feet
Hence,length is 2.8 feet
Answer:
8 ft
Step-by-step explanation:
The area of a paralellagram is b*h. Since we know the base, 15, we can plug this into an equation.
15(h) = 120.
Divide by 15 on both sides to get you 8.
I think it’s 36 cents or .357
We need to solve how much it cost to paint a room with are 459 ft² given that a room with an area of 306 ft² costs $72. The solution is shown below:
Cost per area = $72 / 306 ft²
Cost per area = $0.2353 / ft²
Solving the cost for the similar room:
Costs = $0.2353 * 459 ft²
Costs = $108
The answer is $108.
