Question

perimeter of rectangular garden is 180m and it's length is 50m . find its breadth​

Answer 1

Answer:

perimeter of rectangle=2(l+b)

180m=2(50+b)

180m=100+2b

2b=80

b=40m

Answer 2

Answer:

PERIMETER OF RECTANGULAR GARDEN = 180m

LENGTH =50m

BREADTH = ?

let the breadth be x , then

Perimeter = 2(Length+ breadth)

180m = 2(50+x)

180m=100+2x

180-100m=2x

80m=2x

80÷2m=x

40m=x

breadth =40m
