The perimeter of an equilateral triangle is inches 19 more than the perimeter of a square, and the side of the triangle is 8 inches longer than the side of the square. Find the side of the triangle.

Step-by-step explanation:

s. of. square=l

p of square=4l

s of triangle=8+l

p of triangle=19+4l

p of equilateral triangle=3 × s of triangle

19+4l=24+3l

l=5

s of triangle= 8 + l

=8 +5

=13

the 3rd on is correct
