Respuesta :
length of side = 36 cm
let x be the side of the square then x + 8 is the side of the triangle
perimeter of square = 4x and
perimeter of triangle = 3( x + 8 ) + 4 = 3x + 24 + 4 = 3x + 28
equating the perimeters
4x = 3x + 28 ( subtract 3x from both sides )
x = 28
length of side of triangle = x + 8 = 28 + 8 = 36 cm
length of side = 36 cm
