Question 964968: Tyler has a rectangular garden that measures 10 m wide by 13 m long. He wants to increase the area to 208 m2 by increasing the width and length by the same amount. What will be the width (shorter dimension) of the new garden?

(10+x)(13+x)=208
130+23x+x^2=208
x^2+23x+130-208=0
x^2+23x-78=0
(x+26)(x-3)=0
x-3=0
x=3 ans. for the additional increase of the length & width.
Proof:
(10+3)(13+3)=208
13*16=208
208=208
