Question

Find the perimeter of the triangle. Round to the nearest tenth.
A
25.0
B
17.1
C
12.5
D
7.1

Answer 1

Answer:

B)   17.1

Step-by-step explanation:

g = 5

f = 5

That means we have a 45-45-90 triangle

and the hypotenuse = $\sqrt{2}$ times the length of a leg

Therefore, h = 5$\sqrt{2}$ = 7.1

5 + 5 + 7.1 = 17.1

Note:  If you have not been taught about 45-45-90 triangles, then use the Phythagorean theorem.  OK?
