Area of the square = 100
Area of square = \(s^2\)
\(s^2\) = 100
\(s = 10\)

The square's top side = one side of equilateral triangle

The triangle's sides are equal.

Perimeter = (3)(10) = 30

Answer B

Each side of the square = Each sides of the Triangle = 10

So, Perimeter of the Triangle is 3*10 = 30

Answer will be (B)
