Question

The length of a rectangle is four times its width. If the perimeter of the rectangle is 100 metres, find the length and width of the rectangle.​

Answer 1

Answer:

LET THE width of rectangle is X

THEN ACCORDING TO QUESTION THE LENGTH IS 4X

FORMULA FOR PERIMETER:

$2(l + b)$

PUT VALUE IN FORMULA

$100 = 2(4x + x)$

$100 = 2(5x)$

$100 = 10x$

$x = 10m$

SO THE LENGTH IS 4X=4×10=40m

and breath is10m

Answer 2

Answer:

Length of the Rectangle = 40m

Width of the Rectangle = 10m

Given that ;

Perimeter of the Rectangle = 100m

Let ;

The width be = x

Length = 4x

Formula :

Perimeter of the Rectangle = 2 ( l + w )

P = 2 ( 4x + x )

2 ( 5x ) = 100

10x = 100

x = 100 / 10

x = 10

Hence ;

Width of the Rectangle ( x ) = 10m

Length of the Rectangle ( 4x ) = 4 × 10

= 40m
