A rectangular room is 2 meters longer than it is wide, and its perimeter is 20 meters. Find the dimension of the room.

Answer 1

Find relationship of length(L) and width(w)

L = w+2. (The length is 2 meters longer than it's width)

w

Perimeter = L + W + L + W

20. = (w+2) + w + (w+2) +w

20. = 4w + 4

-4. -4

16 = 4w

16. = 4w

4. 4

4. = w

w = 4

L. = w+2

= 4 +2

L = 6

Answer width is 4 meters and length is 6 meters.
