Question

ans that given example​

Answer 1

3. 11,33

Step-by-step explanation:

x+3x+x+3x=8x=88

x=11

sides are 11 and 33

Answer 2

Answer :

Length of those sides is 11 and 33 cm respectively

Things to know :

A parallelogram is an enclosed figure with four sides that has two opposite sides equal and parallel to each other .

Perimeter is the sum of the boundary of a figure .

Solution :

Let the sides be 1x and 3x

Then the four sides would be 1x , 3x , 1x and 3x

• Perimeter = 1x + 3x + 1x + 3x
• 88 = 8x
• $\sf\implies\::\dfrac{88}{8}\:=\:x$
• 11 = x

Thus the sides would be ,

• 1x = 11 cm
• 3x = 3 × 11
• 3x = 33 cm
