You can put this solution on YOUR website!
length of sides of triangle = 3, 4, and 5
Perimeter of triangle = 3 + 4 + 5
Perimeter of triangle = 12 cm
Let x = length of sides of the square
Perimeter of square = Perimeter of triangle
Perimeter of square = 4x
12=4x%7D%7D%0D%0A%7B%7B%7Bx=4
4cm is the length of the sides of the square

The sides are 3,4,5
they are pythagorean triplets
5 is the hypotenuse
3 & 4 are the legs
Area =1/2 * 3 * 4
Area= 6 cm^2
you can also solve by herons formula
perimeter = 3+4+5 = 12
half perimeter = 6
Area+=+sqrt%28s%2A%28s-a%29%28s-b%29%28s-c%29%29
Area+=+sqrt%286%286-3%29%286-4%29%286-5%29%29
+area+=+sqrt%2836%29
= 6 cm^2
