The perimeter of the right triangle is 12y.
How to find the sides of a right triangle?
A right triangle has one of its angles as 90 degrees.
The sides can be found using Pythagoras theorem.
Therefore,
c² = a² + b²
where
- c = hypotenuse
- a and b are the other legs
Therefore,
4y and 3y are the other legs.
5y is the hypotenuse of the triangle
(5y)² = (4y)² + (3y)²
25y² = 16y² + 9y²
The perimeter of the triangle = 4y + 5y + 3y = 12y
