Hence, the other two adjacent sides are also 7x and 3x.

perimeter = 100 cm

⇒ 3x + 7x + 3x + 7x = 100 cm

⇒ x = 5

so required sides are sides are 35 cm, 15 cm, 35 cm and 15 cm.

other are also the same.

your p. = 100 cm

then u apply the linear equations method.

3x*2+ 7x*2=100

standard form = 3x+7x+3x+7x=100

20x =100

x=100/20

x=5.

so the sides are 15cm,35cm, 15cm,35cm.

hope this helps u !!!!!!!!!!!!!!
