Answer:
The longest side is 32 inches long
Step-by-step explanation:
Let x represent the first side
Since x is 8 in shorter than the second side, we know that we'd need to add 8 to x to get the length of the second side. So the second side is x+8
The third side is 4 times the length of the first side, so the third side is 4
x
.
Perimeter is the sum of the sides, so: (
x
)
+
(
x
+8
)
+
4
x
=
6
x
+
8
We also know that the perimeter is 56
6x+8=56 Subtract 8
6x=48 Divide 6
x=8
The three sides have length: 8, 16,and 32
How to get 16
x+8 x=8 so 8+8 which equals 16
How to get 32
It says the third side is 4 times the second side (s=second side)
So 4xs 4x8=32
