A rectangle has 4 sides: 2 lengths and 2 widths.
What is the perimeter of a rectangle? How do you calculate it if you know the lengths of the 4 sides?

anonymous · Answer

l=14cm and w= 8cm

mathstudent55 · Answer

You have the correct formula above for the perimeter:

P = 2(L + W)

Here, the length, L = 2(x + 6), and the width, W = 3.5x
Plug those values into the formula to get:

P = 2[2(x + 6) + 3.5x]

Now simplify the expression.
