Let's call the shorter side of the rectangle x, then the longer side will be 5x because they are in the ratio of 5:1.
The perimeter of a rectangle is given by the formula:
P = 2(l + w)
where P is the perimeter, l is the length, and w is the width.
We know that the perimeter is 144cm, so we can plug that in:
144 = 2(5x + x)
Simplify and solve for x:
144 = 2(6x)
72 = 6x
x = 12
Now we can find the length of the longer side:
5x = 5(12) = 60
So the length of the longest side is 60cm.
The sides of a rectangle are in the ratio of 5:1.
The perimeter is 144cm.
What is the length of the longest side?
