Question

The perimeter of a parallelogram whose parallel sides have lengths equal to 12 cm and 7 cm
is:
a) 21 cm b) 42 cm c)19 cm d)38 cm

Answer 1

Formula of the perimeter of a parallelogram = Sum of all sides

Two sides(length and breadth) = 12 cm and 7 cm

Perimeter = 12+7+12+7 = 38

Option D) 38 cm

Answer 2

Answer:

Given :-

• Base of Parallelogram = 12 cm
• Height = 7 cm

To Find :-

Perimeter

Knowledge Required :-

Perimeter of Parallelogram = 2(a + b)

• A is the first side or Base
• B is the Second side or Height

Solution :-

Perimeter = 2(12 + 7)

Perimeter = 2(19)

Perimeter = 38 cm

Therefore

$\therefore \sf Perimeter \: is \: 38 \: cm \bigg \lgroup Option \: D \bigg \rgroup$
