Question

the perimeter of a parallelogram is 720 CM length is 12 cm find its area

Answer 1

peri=2(l+b)

720/2=l+b

l+b=360

12+b=360

b=348 cm

area =lb

A=4176 cm2

Answer 2

Perimeter of llgm=720cm=2(l+b)

Length=12cm

720=2(12+b)

12+b=720/2

b=360-12

b=348

Area of llgm=l*b

=12*348=4176cm²
