Question

One side of a || gm is3\4 times its adjacent side.if the perimeter of the ||gm is 70 cm find the sides of the ||gn

Answer 1

Answer:

Sides = 15cm and 20 cm.

Step-by-step explanation:

Let the adjacent side =x

Another adjacent side = 3/4 of x= 3/4x

Perimeter of //gm is 70 cm.

Perimeter of //gm= 2(a+b)

70 = 2( 3/4x +x ) ( take LCM )

70/2 = 3x/4+4x/4 )

35=7x/4

35*4/7 = x

5*4=x

20 = x

1st adjacent sides = 20cm

2nd adjacent sides = 3/4*20 = 3*5=15 cm.
