Question

If the perimeter of a rectangle is 218/15m and its length is 14/3m, find its breadth.

Answer 1

Perimeter = 2( l + b)
218/15 = 2 ( 14/3 + b )
218/15 ÷2 = 14/3 + b
109/15-14/3 = b
b = 109/15 - 70/15
=39 /15
= 13/5 m

Answer 2

Heya !!!



Length of rectangle = 14/3 m


Let breadth of rectangle be X m



Given that,


Perimeter of rectangle = 218/15 m



2 ( L + B ) = 218/15



2 ( 14/3 + X ) = 218/15



14/3 + X = 218/15 × 2


14 + 3X/3 = 109/15


15 ( 14 + 3X) = 109 × 3

210 + 45X = 327


45X = 327 - 210


45X = 117

X = 117/45 = 39/15 = 13/5


Hence,


Breadth of rectangle = X = 13/5 m
