Question

The ratio of the adjacent sides of a parallelogram is as 2:3 and its perimeter is 40cm find its sides of the parallelogram

Answer 1

Answer:

perimeter=40

Semi perimeter=20

then 20 x 2/5=8

20x3/5=12

8,,12,8,12 cms are the sides of the

parallelogram

Answer 2

Step-by-step explanation:

let the adjacent angles 2:3 be 2x and 3x

means that it will be length and breadth

Length=2x

breadth=3x

Perimeter of a parallelogram =2(l+b)

40=2(2x+3x)

40=4x+6x

40=10x

40/10=x

x=4

Therefore, length of a parallelogram=2x

=2×4

=8cm

breadth of a parallelogram=3x

=3×4

=12cm

sides of a parallelogram are 8cm and 12 cm
