Question

A rectangle sheet of paper is 12 1/2 cm long
and 10 2/3cm wide . find it's perimeter?​

Answer 1

Answer:

perimeter of rectangle = 2(L+B)

Step-by-step explanation:

L=12 1/2=23/2cm.

B=10 2/3=32/3cm.

Perimeter (P)= 2(23/2+32/3)cm.

p=2(23/2+32/3)cm.

=2(69+64/6)

=2(133/6)

=133/3

Perimeter of rectangle= 133/3cm.

Answer 2

perimeter of rectangle=2(l+b)

here, l=12 1/2=12×2+1/2=12.5

b=10 2/3=10×3+2/3=10.66

putting the values

2(12.5+10.66) =46.33
