Question

The perimeter of a rectangle is 90 m .It is 30 M long .Its breadth is

Answer 1

Given,
The paremeter of rectangle =90
length of rectangle =30
perimeter formula =2(b+l)
So, the solution is
Perimeter of rectangle =2(b+l)
90=2(b+30)
90/2=b+30
45=b+30
b=45-30
B=15
Breath is 15

Answer 2

Given:

The perimeter of a rectangle=90m

Length of the rectangle=30m

To find:

The breadth of the rectangle

Solution:

The rectangle's breadth is equal to 15m.

We know that the perimeter of the given rectangle can be determined by adding both its lengths and breadth.

So, rectangle's perimeter=2(length+breadth)

Using the given information,

90=2(30+breadth)

90/2=(30+breadth)

45=30+breadth

45-30=breadth

15=breadth

Therefore, the rectangle's breadth is equal to 15m.
