Answer: 8ac+12b+4
Step-by-step explanation: Simplify the expression.
Hope this helps you out! ☺
Area=l*b=l*(l-2)=80(given)
so, l^2 - 2l =80
l^2 - 2l - 80=0
l=10 or -8
l=10,b=10-2=8
perimeter=2(l+b)=2(18)=36
Well, the enlargement would be 3, because 15/5 is 3. So, the new measurements are no 9x15in.
