By adding the three sides.
The perimeter of a triangle is the sum of the lengths of the three sides.If the three expressions in the question are in fact the lengths of thethree sides, then the perimeter is their sum.(7x + 9w) + (2x + 8y) + (2y + 5w) = 9x + 10y + 14w
Add up the sides.
-- Measure or calculate the length of each of its 3 sides. -- Add the lengths of its 3 sides. -- The sum is the perimeter of the triangle.
The perimeter of a triangle is the sum of its 3 sides
the ratio of the perimeter of triangle ABC to the perimeter of triangle JKL is 2:1. what is the perimeter of triangle JKL?
By adding the three sides.
Suppose the side of the square is x cm.Then its perimeter is 4x cm.The perimeter of the square is 3 cm more than that of the triangleso the perimeter of the triangle is 4x - 3 cm.Also, if the side of the square is x cm, the side of the triangle must be x + 112 cm.Then its perimeter must be 3*(x + 112) = 3x = 336 cm.Equating the two expressions for the perimeter of the triangle,4x - 3 = 3x + 336therefore x = 339 cm.The square has sides of 339 cm and a perimeter of 1356 cm.The triangle has sides of 451 cm and a perimeter of 1353 cm.
-- Make sure you have the lengths of all three sides -- Add up the lengths of all three sides to get the perimeter of the triangle.
