Question

A rectangular field has perimeter 186m and breadth 35m .find the length .

Answer 1

p=2(l+b)
=)186/2=l+35
=)93-35=l
=)l=58

Answer 2

petimeter = 2 (l + b)
let l be x
2 ( x + 35 ) = 186
x + 35 = 186 / 2
x + 35 = 93
x = 93 - 35
x = 58
length is 58 m

let ' s check
2 ( 58 + 35 )
2 * 93
186 m

hope this is helpful..
