Question

the length and breadth of a rectangular Park are in the radius 5: 3 and its perimeter is 128 M. find the area of park.

Answer 1

let it be 5x&3x,
then x=16/2=8
length=40
breadth=24
AREA=40*24=960M2

Answer 2

Answer:

Step-by-step explanation:

Perimetre = 2(l+b)

                    2(l+b)=128

length and breadth are in the ratio 5;3, so take

l=5x and b=3x

from this, 2(l+b)=128

                 2(5x+3x)=128

                 2(8x)=128

                 16x=128

                x=128/16=8

so we find x=8

now 5x=5*8=40

       3x=3*8=24

therefore area=l*b

                        40*24=960cm sqaure
