The perimeter of a rectangle is =12 1/3 cm.
it's breadth is =2 1/3 cm
TO FIND:
____________
The length of the rectangle
SOLUTION:
_______________
As per the question,
the perimeter is= 12 1/3 cm
=12×3+1/3cm
=37/3 cm
the breadth is=2 1/3 cm
=2×3+1/3
=7/3 cm
the formula of the perimeter of a rectangle is=2×( length+breadth)
=>37/3 cm=2×( length+7/3 cm)
=>37/3cm/2=length+7/3cm
=>37/6cm= length+7/3cm
=>length=(37/6–7/3)cm
=>length=(37–14/6)cm
=>length=23/6 cm
=>length= 3 5/6 cm (in mixed fraction)
