Question

The length or width of a rectangular park are in the ratio 3:2 and it's perimeters is 160m. Find the area of a park.

Answer 1

Answer:

length=48m, breath=32m

Area of rectangular park=1536m2

Step-by-step explanation:

let length=3x

let length=3xbreath=2x

let length=3xbreath=2xperimeter of rectangle=2(l+b)

let length=3xbreath=2xperimeter of rectangle=2(l+b) 160 = 2(3x+2x)

let length=3xbreath=2xperimeter of rectangle=2(l+b) 160 = 2(3x+2x) 80 = 5x

let length=3xbreath=2xperimeter of rectangle=2(l+b) 160 = 2(3x+2x) 80 = 5x X =16

now,

length = 3*16 = 48cm

breath = 2*16= 32

therefore,

area of park = l*b

= 48*32

= 1536 m2
