Question

the perimeter of a rectangle is same as the perimeter of a square of side 15 CM if length of the rectangle is 17 cm find its breadth​

Answer 1

Answer:

Given that perimeter of rectangle =perimeter of square

Then, 2(l+b)=4×one side

2(17+b)=4×15

2(17+b)=60

(17+b)=60/2

(17+b)=30

b=30-17

b=13

So, breadth of rectangle is13cm

Hope it helps you....

Answer 2

Given:

Side of sqaure=15 cm

Length of rectangle=17 cm

Perimeter of rectangle=perimeter of square

To find:

Breadth of rectangle=?

Solution:

Here we have side of square=15 cm

so,let's find its perimeter

Perimeter of square=4×side

= 4×15

= 60 cm

Now,lets find perimeter of rectangle to get its breadth

Perimeter of rectangle =2 (l+b)

60=2×17 +2b

60=34+2b

60-34=2b

26=2b

b=26/2

. :b=13

Ans.The braedth of rectangle is 13 cm respectively.
