Kayla has a rectangler garden that measures 10 m wide by 13 m long. He wants to increase  the area to 208 m by increasing the width and length by same amount. What will be the length (longer dimension) of the new garden.?

Assuming the width and length are increased by x, 

Then (10+x)(13+x)=208

         10*13+23x+x^2=208

         x^2+23x-78=0

         (x+26)(x-3)=0

So x=3

Therefore the length of the new garden is 3+13=16 m.
