Question

the side of a parellogram is in the ration 3:7 and the perimeter of a parellogram is 200 cm . find the length of the sides of a parellogram​

Answer 1

Answer:

140 CM

Step-by-step explanation:

Ratio 3:7

Total ratio= 3+7=10

Perimeter = 200cm

Length of first side: if 10= 200cm

3=?cm

?=(3×200cm)÷10= 60cm

Length of second side: if 10 =200cm

7=? cm

?= (7×200cm)÷10 =140cm

Answer 2

Answer:

let the sides of parallelogram is3x,7x

perimeter of parallelogram=2(a+b)

2(3x+7x)=200

2*10x=200

10×=200/2

10x=100

×=100/10

x=10cm

Then, putting the value of x

3x

3*10

30cm ANS

7x

7*10

70cm ANS.
