the number (x) is 120.
Explanation:
<em>100% + 60% = 160% = 1.6 </em>
<em />
<em>(just multiply it by 1.6 because it is equal to 60%)</em>
Let
x-------------> amount added <span>to each side
</span>A-------------> area increased----------> 84 ft²
we know that
A=(10+x)*(5+x)=84-----------> 10*5+10*x+5*x+x²
50+15x+x²=84----------> x²+15x-34=0

</span>x1=-17
x2=2
the answer is x=2 ft
