Question

this is a vest question it is brilient question

Answer 1

take x add both and write reduced area

Answer 2

length be x and breadth be y
then
2(x+y)=180
x+y=90
given
($\frac{110x}{100}$)($\frac{85y}{100}$)=xy-130
0n solving we get xy=2000
(x+y)^2-4xy=(x-y)^2
we get x-y=10
on solving the two equations we get x=50,y=40
