Question

The perimeter of rectangle is same as that of square of side 15cm if length of rectangle is 17 cm find it's 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

Answer:

12

Step-by-step explanation:

as the perimeter of rectangle and square is equal so

p of rectangle = p of square

p rect. = 15×4

p rect. = 60 .. -. 1 eq.

p rect. = 2( l× b)

= 2 ( 17 × b )

60 = 34 × 2 b

60 - 34 =2b

26 =2 b

breadth = 12
