Question

the lenght of the rectangular park is 10 m more than its breadth,perimeter of park is 180 m find out the dimensions of park using linear equations in two variables​

Answer 1

let breadth =x meter & length =y meter

given x+10=y

perimeter =180=2(l+b)

2(x+x+10)=180

(2x+10)=90

2x=90-10

x=80÷2

x=40 meter

breadth=40 meter

length=x+10=40+10=50meter
