Question

the perimeter of a
parallelogram is 50 cm.one side is 1.5 times the other. the sides of the parallelogram are​

Answer 1

Step-by-step explanation:

Using the formula

P=2(a+b)

Solving forb

b=P

2﹣a=50

2﹣1.5=23.5

Answer 2

Answer:

10 and 15

Step-by-step explanation:

Let the two sides of parallelogram be a and b

one side is 15.cm times the other

⇒ a x 1.5 cm = b

we know that perimeter of a parallelogram is 2(l+b)

    here it is 2(a+b)  = 2(a+ 1.5 a cm ) = 50 cm (given)

⇒ 2a + 3a cm = 50 cm

⇒5a = 50 cm

⇒ a = 50 cm / 5

⇒ a = 10 cm

then b = a x 1.5cm

⇒ b = 10  x 1.5 cm

⇒ b = 15 cm  

so the sides of parallelogram are 10 cm and 15 cm
