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
Here are the coordinates :)
The answer is 0.49
0.7 x 0.7 = 0.7^2
Answer:
so what we have to do first is multiply 9*10
which is 90 now we divide by two to get 45
now we multiply 45 by 20 to get
900
Hope This Helps!!!
