Perimeter of a rectangle = 2(l + b)
Given we have to write in x and y
So perimeter = 2(x + y) = 40
So equation is 2(x + y) = 40
=> x + y = 20
2) Ratios can be simply written as
5x : 3y
3) Let father be x years and son be y years
So equation is
x + y = 73
4) Let 1 table's cost be x
Let 1 chair's cost be y
So equation is
2x + 3y = 5400
Hope it helps dear friend ☺️✌️
