Question

Find the length and breadth of rectangle given below perimeter is 72 m 5x + x - 4

Answer 1

Step-by-step explanation:

perimeter 72=2(5x+x-4)

6x-4=36 x=40/6=6.7

so length is5x=33.5m

and breadth x-4=6.5-4=2.5

Verify

perimeter =72=2(33.5+2.5)

=36×2=72

hope it helps you thanks

Answer 2

Length = 34

Breadth = 4

Explanation:-

Given that:-

The perimeter of the rectangle given

=> 72cm

cmThe perimeter of the length given

=> 5 +4

The perimeter of the breadth given = x-4

formula using:-

The perimeter of the rectangle = 2(l+b)

solution:-

$72= (5y+4,x-4)$

$72= (5y,x)$

$72=2(6x)$

$72 = 12x$

$x = \frac{72}{12}$

$= > 6$

Putting values

$length = 5x+4$

$=>5×6+4$

$=>30+4$

$= > 34$

$Breadth = x-2$

$= > 6 - 2$

$= > 4$
