Answer:
W = 4.95
Step-by-step explanation:
You want to start by writing down what you know, and forming a system of equations.
L= length W= width
2L+2W=14.7
L= 2.4
On the left side of the equation, you're adding all your side lengths, and on the right, is the total perimeter. (Also could be written L+L+W+W = 14.7)
You would then substitute L from the bottom equation into the top equation to get:
2(2.4) +2W=14.7
Solving:
4.8+2w=14.7
W= 4.95
To check your answer simply add all the sides together and make sure it equals your perimeter. You can also plug W and L back into the original equation.
Volume = 10,700
V = LWH
L = 29.4
W = 16.7
H = 21.8
All we need to do is multiply them all together and then round the answer to get our final answer to the hundreds place.
V = LWH
V = 29.4(16.7)(21.8)
V = 490.98(21.8)
V = 10703.364
Then, we need to round it to the hundreds place.
V = 10,700

I think its the last one if you get it wrong im SOOO sorry
