Question

a rectangular sheet of paper is 15 3/4 cm long and 12 1/2cm wide . Find its perimeter.
​

Answer 1

perimeter of rectangle = 2(l +b)      where l = length

                                                                  b = breadth

given,

l = 12 1/2 , b = 15 3/4

perimeter = 2( 12 1/2 + 15 3/4)

              = 2( 25 / 2 + 63 / 4)

              = 2(50 + 63)/ 4

              = 2( 113/ 4)

              = 113/2

              = 56.5 cm

Answer 2

Answer:

___________________

56.5 cm

___________________

Step-by-step explanation:

___________________

length = 15 3/4 cm = 63/4

breadth = 12 1/2 cm = 25/2

Perimeter of a rectangle = 2(l + b)

= 2 (63/4 + 25/2)

2 ( 63 + 50 /4)

2 ( 113/4 ) = 2 × 28.25 = 56.5 cm
