Question

The Perimeter of a rectangle of length 18 cm and
breadth 12 cm is equal to the perimeter of a square. What
is the length of the side of that square?

Answer 1

Step-by-step explanation:

perimeter of rectangle = perimeter of square

2 ( l + b ) = 4

2 ( 18 + 12 ) = 4

= 30 cm = 2 cm

side = 30 / 2

side = 15 cm

Answer 2

Answer:

2(12+ 18)

= 30 × 2

= 60

Explaination

Perimeter of rectangle : 2×( L+B )

So,

2×( 12 + 18 )

2× 30

60
