find the length and width of a rectangular lot with a perimeter of 100 meters, if the length is 5 meters more than the width

Question

I need the length and the width of the rectangle.

Answer 1

Perimeter is twice the sum of length and width. So the sum of length and width is half of 100m=50m.

Length is 5m more than the width so length+width=(width+5)+width=50m.

So two widths = 45m, one width=22.5m and length is 27.5m.
