Perimeter means finding the distance around the triangle.
The simplest way to find the perimeter of a triangle is to add up the length of all of its sides

so perimeter of the large triangle = x + y + 5 +20

What is the third side

ASHA 777 [7]

Answer:

A. 2.82 m

Step-by-step explanation:

The missing side we are trying to find is the hypotenuse, this is because it is the longest side of a right triangle.

The Pythagorean Theorem is used:

$a^2+b^2=c^2$

Plug in the given numbers (2), accordingly:

$2^2+2^2=c^2\\4+4=c^2\\8 = c^2\\$

Take the square root of both sides:

$\sqrt{8} =\sqrt{c^2}$

2.82 ≈ c
