Question

the perimeter of a rectangular park is 220 m. I f the breadth is 10 times of length, find the length and breadth.​

Answer 1

Answer:

perimeter is 220

let length x

so breadth will be 10 x

hence perimeter of reactangle is 2(l+b)

putting values to formulae

2(x+10x) =220

2*11x =220

22x. = 220

x = 220 / 22

x= 10

hence length = 10.

so breadth = 10*10

= 100

Answer 2

Answer:-

Given,

Perimeter of rectangular park

= 220 m

Let the length and breadth of the park be l and b

According to the question,

2 ( l + b ) = 220 •••••• (i)

b = 10l •••••• (ii) , put in (i)

2 ( l + 10l ) = 220

11l = 110

l = 110/11

l = 10 m , put in (ii)

b = 10 * 10

b = 100 m
