4. Find the perimeter of a rectangle whose sides are:
(a) 12 cm and 9 cm (b) 24 m and 20 m​

Answer 1

Answer:

(i)perimeter = 42cm

(ii)perimeter = 88m

Step-by-step explanation:

perimeter of a rectangle is 2(l+b)

(i) where l= length = 12cm

   and b = breadth = 9cm

    therefore,

    2(12 + 9) = 2(21)

    = 42cm

(ii) l = length = 24m

   b = breadth = 20m

   therefore,

   2(24 + 20) = 2(44)

   = 88m
