Question 764977: The area of a rectangle is 221 square metres ahead its length 4
metres more than its breadth. What is the measure of its breadth? Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Breadth = x
Length = x + 4
Area = length * breadth
221 = (x + 4) * x
x^2 + 4x = 221
x^2 + 4x - 221 = 0
(x + 17)(x - 13) = 0
x + 17 = 0
x = -17 (no answer x <0)
x - 13 = 0
x = 13
Breadth = 13m
Length = 17m
Hope this helps.
