Question

One side of the parallelogram is 25 cm larger than the other, perimeter 122 cm. Find the sides.

Answer 1

Answer:

Step-by-step explanation:

let the sides be x and 25+x

x + 25+x + x +25+x = 122

4x + 50 = 122

4x = 72

x = 18 cm

Sides are 18 cm, 43 cm, 18 cm, 43 cm

Answer 2

Answer:

18 cm and 43 cm

Step-by-step explanation:

Given that,

One side of paralleolgram is 25 cm larger than the othe.

Also given that,

Perimeter of paralleolgram = 122 cm

To find the sides.

Let one of the side be x cm.

Therefore, another side = (x+25) cm

Now, we know that,

Perimeter = 2(sum of sides)

=> p = 2(x + x + 25)

=> 2(2x+25) = 122

=> 2x + 25 = 122/2

=> 2x + 25 = 61

=> 2x = 61-25

=> 2x = 36

=> x = 36/2

=> x = 18

Therefore, we will get,

=> x +25 = 18+25 = 43

Hence, required sides are 18 cm and 43 cm.
