Question

Help How do u get The are and the perimeter with only 2 sides???

Answer 1

60

Explanation:

A squared + B squared = C squared

15 squared + 20 squared = C squared

225 + 400 = C squared

625 = C squared

Use radicals to find the square root of 625

Which is 25

C = 25

25 + 15 + 20 =

60

Answer 2

60

Explanation:

Since this is a right triangle, the longest side can be solved using the Pythagorean Theorem

x^2 + y^2 = z^2

So

15^2 + 20^2 = 225 + 400 = 625 = 25^2.

So 25 is hypotenuse.

Add them all together : 25+15+20 = 60.

So your answer is 60.
