Answer:

Step-by-step explanation:

Using the pythagorean theorem, we can solve to find C.

a^2 + b^2 = c^2

So it will be 15^2 + 20^2 = c^2

Simplify:

225 + 400 = c^2

625 = c^2

Square root both sides of the equation and you will get:

25 = c

c = 25

(a) The length of the unknown side is 25 yd

For perimeter, just add 20 + 15 + 25

(b) So the perimeter is 60 yd

The formula for area of a triangle is:

Area = (Base x Height) / 2

Now, we can plug in the numbers.

Base = 15

Height = 20

(15 x 20) / 2

300 / 2

= 150

(c) The area of the triangle is 150yd^2
