Question

in a rectangle of perimeter 50cm one side is 10cm longer than the other what are the length of the sides​

Answer 1

Answer:

b = 15cm

Step-by-step explanation:

perimeter of rectangle is = 2 ( l + b )

50cm = 2 ( 10cm + b )

50cm = 20cm + 2b

50cm - 20cm = 2b

30cm = 2b

b = 15cm

Answer 2

Step-by-step explanation:

one side =10cm

let ABCD the rectangle.

therefore,AB=CD length....... ........... 1

andAC=BD breadth .......................... 2

let AB the given side

therefore,AB=10cm....... 3

then from1

CD=10cm

perimeter of rectangle=2(l+b)

50 =2x(10+b) ..from3

50=20+2b

50-20=2b

30=2b

b=30\2

b=15cm

from2

AC=BD=15cm

answer..

the length of other sides are 10cm,15cm,15cm.
