Question

4.The perimeter of a square, a regular pentagon and a regular hexagon are equal.
What is the least possible perimeter that the three shapes can have?​

Answer 1

Answer:

120cm it is correct answer

Answer 2

Answer:

60cm

Step-by-step explanation:

Let each side of the square be x.

Therefore,

perimeter of square=4x.

Let each side of regular pentagon be y.

Therefore,

perimeter of pentagon=5y.

Let each side of regular hexagon be z.

Therefore,

perimeter of hexagon=6z.

According to question,

4x=5y=6z.

Since,

LCM of 4,5,6 = 60.

Therefore,

Least possible perimeter of three shapes=60 cm
