The perimiter of a shape is the distance around its edge, in this case 10 +17 + 21 giving a total of 48 inches, or four feet if you want to convert it.
A triangle cannot have four sides.
17 inches
Add all three sides. Perimeter = 15 + 17 + 10 = 42
To find the perimeter of a triangle, you simply add the lengths of all three sides together. In this case, the perimeter would be 15 cm + 17 cm + 10 cm = 42 cm. So, the perimeter of the triangle with sides measuring 15 cm, 17 cm, and 10 cm is 42 cm.
A triangle cannot have four lengths!

228 inches, what you do is add, 97+97+17+17
18.1 square inches.
It is 2*(50 + 17) = 2*67 = 134 inches.
