Find the perimeter of the rectangle? Needs to be in standard form

vladimir2022 [97]

Answer:

6b - 4a + 22 units

Step-by-step explanation:

Perimeter = 2(length + width)

= 2(3b - 4a + 5 + 6 + 2a)

= 2(3b - 2a + 11)

= 6b - 4a + 22 units

Find the missing side lengths. Leave your answers as radicals in simplest form.

Citrus2011 [14]

This is the isosceles right triangle, the diagonal of a square, the thing that so upset the Pythagoreans. The two sides and diagonal of a square are in ratio $1:1:\sqrt{2}$ so we get

$u = v = 8$

We could have also gotten this using Trig:

$u = (8 \sqrt{2}) \sin 45^\circ = 8 \sqrt{2}/\sqrt{2} = 8$

$v = (8\sqrt{2})\cos 45^\circ = 8$

Or by recognizing u=v because remaining angle is 45 so this must be isosceles so

$u^2 + u^2 = (8 \sqrt{2})^2$

$2u^2 = 2 (8^2)$

$u = 8$
