Hi,

a square garden has a side of (x-7y)m. what would be the effect on it's area if the lenght is doubled.

A(square) = side^2 = highlight%28%28x-7y%29%5E2%29

length doubled

 A = [2(x-7y)]^2 = highlight%284%28x-7y%29%5E2%29  

That is the Area would increase by 4 times (the effect of squaring the 2)

for ex: tripling the length would result in Area increasing by 9 times
