Question:

the perimeter of a rectangle can be found by using the formula p= 2l+ 2w where l is the length and w is the width of a rectangle. what is the width of a rectangle with a perimeter of 50 meters and a length of 16 meters?

Answer:
P = 2l+ 2w,------------------(1)
where l is the length and w is the width of a rectangle.

Here given that,

Perimeter, P = 50 meters
Length, l = 16 meters.

Plug these values in the given formula,

==> 50 = 2(16)+ 2w

==> 50 = 32 + 2w

Subtract 32 from both sides...

==> 50 - 32 = 32 + 2w - 32

==> 18 = 2w

Divide both sides by 2

==> +18%2F2+=+2w%2F2

==> +9+=+w

That is width = 9 meters...

Hope you found the explanation useful.
