Question

The peumeteu of a rectangle of length 18cm and Breadth 12cm is equal to the
perimeter of a square What is the length of the side of that square?​

Answer 1

Answer:side=15 cm

Step-by-step explanation:

Perimeter of rectangle=perimeter of square

2(l+b)=4*side

2(18+12)=4*side

30 cm=2*side

Side=30/2

Side=15 cm

Answer 2

Answer:

Step-by-step explanation:

The perimeter of a rectangle = the perimeter of a square

i.e. 2(length+breadth) = 4a

Given that,

Length = 18cm

Breadth = 12cm

Now,

2(l+b)=4a

2(18+12)=4a

2(30)=4a

60=4a

4a=60

a=60/4

.'. a = 15cm

Length of the side of the square is 15cms.

Done!!
