Question

The width of a rectangle is 2cm less than its length. the perimeter of the rectangle is 16 cm. What is the length of the rectangle? show work please

Answer 1

If the perimeter is 16, then 16 must be split up into 4 values. Where two are x and the other two are x-2.

If you have a quick look at 16, try to split it up.
E.g. 6 = 3+3

and 10 = 5 + 5

Then the lenght is 5 and the width is 3

Answer 2

You could also use algebra, however, this is just as simple.

Answer 3

p = 2l + 2w

16 = 2l + 2(l-2)
16/2 = l + (2(l-2))/2
8 = l + l - 2
10 = l + l
10 = 2l
10/2 = l
5 = l
w = l-2
w = 3, l=5

Answer 4

There you go.
