Question 239304
Let x=how much you must increase the length of each side to have the area of the flower bed be 187'
(x+30)(x+20)-(30*20)=187 new area-old area=187
x^2+50x+600-600=187
x^2+50x-187=0
x=3.5' Quadratic formula below.
x/2 = 3.5/2 = 1.75' width of the flower bed is 1/2 of the increase in length of each side.
