Question

Please help me on this question​

Answer 1

≈ 35,3 m

Explanation:

First we need to find the third side of the right-angled triangle by the Pythagorean theorem:

`{16}^(2) + {3}^(2) = 265`

`265 > 0`

`the \: third \: side \: is \: √(265)`

And now we can find the perimeter:

P = 16 + 3 + √265 ≈35,3 (m)

Answer 2

Explanation:

For a RIGHT triangle, you can use Pythagorean Theorem to calculate the length of the hypotenuse:

Hypotenuse^2 = leg1 ^2 + leg2 ^2

Hypotenuse^2 = 3^2 + 16 ^2

Hypotenuse ^2 = 265 sqrt both sides

hypotenuse = 16.3 m

Now the perimeter is just all three sides added together:

3 + 16 + 16.3 = 35.3 m
