Question

an equilateral triangle and a square have the same perimeter. The sides of the square are 3 times some number, K. The sides of the triangle are one more than twice the length of the square, k. What is the side length of each.

Answer 1

S=3K

K=S/3

T=1+2K

4S = 3T = 3(1+2S/3)= 3+2S

4S = 3+2S

2S =3

S = 3/2 =

side of the square

S= 3K K = S/3 = 1/2

T = 1+2(1/2) = 2 = side of the triangle

4(3/2) = 3(2)

6 = 6
