Problema Solution
the length of a rectangle is 5 ft longer than its width. if the perimeter of the rectangle is 46 ft, find its area.
Answer provided by our tutors
Let 'l' and 'w' stand for the length and width of the rectangle.
We can write:
l=w+5
2l+2w=46
........
Solving for l and w , we get:
l=14 ft
w=9 ft
Therefore the area is:
area=wl=9*14=126 ft^2
