Question

INDA
if the area of a field is 72 sq m and it's lenght is 9 m . Find its breadth and perimeter​

Answer 1

Step-by-step explanation:

Let the breadth of the field be x.

We know that area of a rectangle = l×b

= l × x

given,

l = 9m

area = 72 sq.m

So,

$9x = 72$

$x = \frac{72}{9}$

$x = 8m$

Therefore breadth = 8m

perimeter of rectangle = 2(l + b )

perimeter = 2(9+8)

perimeter = 2(17)

perimeter = 34m
