Question

What is the perimeter, in centimeters, of Trian

Answer 1

For the given right triangle, the perimeter is 60cm, so the correct option is D.

How to get the perimeter of the triangle?

We can see a right triangle, by using the Pythagorean theorem we can get the missing cathetus:

$a^2 + (20cm)^2 = (25cm)^2$

$a = \sqrt{(25cm)^2 - (20cm)^2} = 15cm$

Now we know the measure of the 3 sides, then the perimeter of the given triangle is:

P = 15cm + 20cm + 25cm = 60cm

The perimeter of the triangle is 60cm.
