A. 18.83
B. 204.7
C. 29.04
D. 34.5

Answer 1

The answer is C. 29.04
You use the Pythagorean theorem for the diagonal side because it’s a right triangle then you add all the sides and get C

Answer 2

Answer:

Option C - 29.04

Step-by-step explanation:

A to C is 9

A to B is 8

C to B is ?

$a^{2} + b^{2} = c^{2}\\ 9^{2} + 8^{2} = c^{2}\\81 + 64 = 145\\c = \sqrt{145} \\c = 12.04$

Perimeter = a + b + c

                = 9 + 8 + 12.04

               = 29.04
