Question

if the perimeter of a square is 40 m find the length and breadth of the rectangle are given that breath is 1 by 3 of the length

Answer 1

Let length be ( x ) m and breadth be ( x / 3 ) m

Perimeter = 40

2( length + breadth ) = 40

Length + Breadth = 40

x + ( x / 3 ) = 40

( 3x + x ) / 3 = 20

4x = 20*3

x = ( 20 * 3 ) / 4

x = 5 * 3

x = 15

Hence, Length = 15 m

Breadth = ( 15 / 3 ) m = 5 m

Answer 2

Heya !!




Let Length of rectangle be X m.


Breadth of rectangle = X/3 m




Perimeter = 40 m


2 ( l + b ) = 40 m




x + x/3 = 20



3x + x = 20×3




x = (20×3/4)



x = 15 m




Length of rectangle = X = 15 m



And,



Breadth of rectangle = x/3 = 5 m
