Question

Find the length
If the area of a square is 100 cm and its perimeter is the same as the perimeter of an
equilateral triangle, what is the length of each side of the triangle?
​

Answer 1

perimeter of square is 40 cm.

Step-by-step explanation:

Area of square = (Side) × (Side)

100 = side × side

= √100

= 10

10 cm. is side. . . . .

Peremeter of square = side × 4

10 × 4

40 cm.

40 cm is peremeter of square.

Answer 2

Answer:

40/3

Step-by-step explanation:

Area of square is 100 cm

each side of square = l

Area of square = l×l or l²

100 = l²

100 = 10 × 10

So l is 10

So perimeter of square = 4l that is 4(10)

= 40

So perimeter of triangle = perimeter of square

perimeter of triangle = 40

since it is an equilateral triangle all sides are equal

Hence each side = 40/3
