Question

I rlly need some help please if ur big brains im going to be asking multiple questions right now

Answer 1

You can break the shape up into a rectangle and a right triangle.

Use your trig ratios to find the missing sides.

Add all the sides up and you have your perimeter!

//

$p = 2(l) + 2(w)$

$p = 2(10) + 2(4)$

$p = 28$

//

$tan = \frac{opp}{adj}$

$\tan(45) = \frac{10}{adj}$

$adj = \frac{10}{ \tan(45) }$

$adj = 10$

${a}^{2} + {b}^{2} = {c}^{2}$

${10}^{2} + 10 {}^{2} = {200}^{2}$

$\sqrt{200} = 14.14213562$

//

$p = 10 + 4 + (4 + 10) + 14.14213562$

*notice how one of the 10 is left out because it is inside the shape so we can't use that to find perimeter.

$p = 42.14$
