Question

the length of a rectangular Garden is 8 more than its breadth find the length and the breadth of the garden if its perimeter is 280 m

Answer 1

You can do it by

Putting value of L

In 2(L+B)

Answer 2

let breadth of the field be X
then , length = 8x
perimeter = 2(l+b)
280=2( X +8x )
280= 2x+ 18x
20x = 280
X= 280/20
X = 14
putting 14 at the place of X
length= 8x = 8 × 14 = 104
breadth = 14
