PLEASE HELP, WILL GIVE 20 POINTS.

Mathematics
1 answer:
OverLord2011 [107]3 years ago
6 0

Answer: 200cm^{2}

Step-by-step explanation:

To double the dimensions, you must multiply both the length and width by 2, so instead of just l*w=a, you have 2l*2w=b, which can be simplified even further to 2*2*l*w=b

Now, multiply the 2s together to get 4, making the equation 4lw=b. Since lw is a, and b is 4 times as much as a, you just need to multiply the original area by 4 to get the new area.
