Question

HELP!!!! WILL MARK BRAINLIEST!!! what is the perimeter???????

Answer 1

Answer:

11 + $\sqrt{65}$

Step-by-step explanation:

The base of the triangle = 7 units ( count squares )

The right side = 4 units

Since the triangle is right, use Pythagoras' identity to find AB

The square on the hypotenuse (AB) is equal to the sum of the squares on the other 2 sides, that is

AB² = 7² + 4² = 49 + 16 = 65 ( take the square root of both sides )

AB = $\sqrt{65}$, thus

Perimeter = 7 + 4 + $\sqrt{65}$ = 11 + $\sqrt{65}$
