Question 548970
If Jim increases each side by 10%, the new dimensions are
30+30*.1=30+3=33
and 
20+20*0.1=20+2=22

So the garden now measures 33 by 22.   
Using the formula 
{{{A=l*w}}}, we can find this new area.

  
I will let you try this. Let me know if you are unsure about anything or how to finish the question:)
