Question

the length and breadth of a rectangular park are in the ratio 5:3 and its perimeter is 125 find the area of the park ​

Answer 1

Answer:

Step-by-step explanation:

Let length of park =5x

Let breadth of park =3x

Perimeter=2(l+b)

125=2(5x+3x)

125=2(8x)

125=16x

x=7.81

Length=5x7.81=39.05

Breadth=3x7.81=23.43

Area=39.05 x 23.43

= 914.941

Answer 2

Answer:

Step-by-step explanation:

Length=5x

Breadth =3x

Perimeter of rectangle = 2(L+B)

                               125 = 2(5x +3x)

                               125 = 2(8x)

                               125 = 16x

                          125/16 = x    

                              7.81 = x

Length=5x = 5 X 7.81 = 39.05

Breadth =3x = 3 X 7.81 = 23.45

Area of rectangle = length X breadth

                             = 39.05 X 23.45

                             = 914.9415
