Question

the length and breadth of a rectangle are 5 3/4 cm and 2 7/8 cm respectively.find its perimeter.

Answer 1

Step-by-step explanation:

length=5 3/4

breadth =2 7/8

first we should convert into improper fraction.

5 3/4 = 23/4

2 7/8 = 23/8

perimeter of a rectangle = 2(l+b)

=2(23/4+23/8)

lcm of 4 and 8 is 8.

so,

=2(46/8+23/8)

=2(89/8)

=2/1(89/8)

=89/4

I think this will be the correct answer.
