Question

Find the perimeter of parallelogram ABCD in which AB=12cm and BC=7cm​

Answer 1

Answer:

Step-by-step explanation:

in a parallelogram the opposite sides are equal and parallel

the perimeter is AB + BC + CD + DA

now AB = CD and BC = DA

so the perimeter is AB + BC + AB +BC

= 12 + 7 + 12 + 7

= 38cm

Hope this answer helped

Answer 2

Answer:

let AB and BC is side of parallelogram

AB= 12 cm

BC=7 cm

perimeter of parallelogram = $2(side1 + side2) \\ \\ 2(12 + 7) \\ \\ 2(19) \\ \\ premiter \: of \: parallelogram \: = 38$
