Question

Find the perimeter of the rectangle having 4 3/4 cm length and 3 1/2 cm breadth​

Answer 1

Answer:

Hence, perimeter of rectangle = 33/2 cm

Step-by-step explanation:

Given,

Length of rectangle, (l) = 4 3/4 cm = 19/4 cm

Breadth of rectangle, (b) = 3 1/2 cm = 7/2 cm

We know that,

Perimeter of rectangle = 2(l + b)

So,

Perimeter of rectangle = 2(19/4 + 7/2) cm = 2(19/4 + 14/4)

= 2(33/4) cm

= 2 × 33/4

= 33/2 cm

Hence, perimeter of rectangle = 33/2 cm

Answer 2

Answer:

please mark as brainliest. follow me (your choice)

Step-by-step explanation:

perimeter= 2 (l+b)

length= 4 3/4 or 19/4

breadth= 3 1/2 or 7/2

lcm of denominators = 4

19×1 =19 7×2 = 14

4×1 4 2×2= 4

19/4+14/4

33/4 × 2

= 8 1/4

8 1/4 ×2 = 16 2/4

or 16 1/2
