Perimeter of a rectangle is 20 m. Its length is2 m greater than its breadth. (Take breadth as y) PLS TELL RALLY CONFUSED IN THIS QUESTION ​

Answer»

let the BREADTH be y m

then,it's length be y +2 m

perimeter of a RECTANGLE = 2(y + y +2)m

= 2y + 2y +4

= 4Y + 4 m

According to the question:-

4y + 4 = 20

4y = 20 - 4

y = 16 ÷ 4

y = 4

breadth = 4 m

length = y + 2 m

= 4+2 m

= 6 m
