Question

i) Find the perimeter of a rectangle in which:
a. Length = 15cm and breadth = 10cm
b. Length = 24cm and breadth = 6cm
c. Length = 42m and breadth = 12m​

Answer 1

perimeter = 2 ( l+b) rule

Answer 2

Step-by-step explanation:

a. length=15cm

breadth = 10cm

$perimeter = 2(l + b) \\ 2(15 + 10)cm \\ 2(25)cm \\ = 50cm$

b. length = 24cm

breadth = 6cm

$perimeter = 2(l + b) \\ 2(24 + 6) cm \\ 60cm$

c. length = 42m

breadth = 12m

$perimeter = 2(42 + 12)m \\ 2(54)m \\ 108m$
