Question

The perimeter of a rectangle is same as the perimeter of a square of sides 15 cm.If length of the rectangle is 17 cm, find its breadth.
​

Answer 1

Answer:

Breadth = 13

Step-by-step explanation:

P of square = side × 4

= 15 × 4

= 60

Let breadth of rectangle be x

P of rectangle = 2 ( l + b )

60 = 2 ( 17 + x )

60. = 2x + 34

60 - 34 = 2x

26/2 = x

13 = x

Answer 2

Step-by-step explanation:

Given:

perimeter of rectangle = perimeter of square

side of square = 15cm

perimeter of square = 4×side

= 4×15

= 60cm

so , perimeter of square = perimeter of rectangle

60 cm= 60cm

ln rectangle:

length = 17 cm

perimeter =60cm

breadth. = x

perimeter of rectangle = 2(l +b)

60 =2 (17+x)

60/2 = 17 + x

30-17 = x

13. =. x

Therefore the breadth of rectangle is 13 cm.
