Answer 1

C) 4 is my choice. Let me explain ....

Answer 2

1/2( L +W) = 3 a side of the equilateral triangle.

So, 1/2(L + W) = perimeter of equilateral triangle because an equilateral triangle has congruent sides.

Perimeter of rectangle is 2L + 2W = 2(L+W)

2(L+W) = 4 times 1/2(L + W).

2(L+W) / [(1/2) (L+W)] = 2 divided by 1/2 = 4.
