Question

the perimeter of a rectangular park is 180 m. It ratio of its length and breadth is 2 : 1 find the area of the rectangle​

Answer 1

Perimeter = 180m
Let the length be 2x
Breadth be 1x
Perimeter = 2(l+b)
180 = 2(2x+1x)
180 = 2(3x)
180 = 6x
x = 180/6
x = 30

Hence the value of length and breadth will be,
Length = 2x = 2*30 = 60m
Breadth = 1x = 1*30 = 30m

Area of the rectangular park = l*b
= 60*30 = 1800m^2

Answer 2

Answer:

length=60

breadth=30

Step-by-step explanation:

so,the perimeter of rectangular park is 180m.And the perimeter of rectangle is 2 (l+b)

here let length be 2x

and breadth be 1x

now we have 2 (2x + 1x )= 180m

3x = 180÷2

x=90÷3

x=30

2×30=60 length

1×30=30 breadth
