Question

frame linear equation in two variables (x&y)representing the given information :if 10 is subtracted from the length & breadth of a rectangle then its perimeter is 60​

Answer 1

then it is fgUgnn bbc dddfg 50

Answer 2

Let the length be x and breadth be y

So,

Perimeter of a rectangle =2(x+y)

A/q,

2(x-10+y-10)=60( this can be the answer)

2(x+y-20)=60

2x+2y-40=60

2x+2y=60+40

2(x+y)=100

x+y=50
