How do i find the area and perimeter?

using the pythagorean theorem, find the length of line TU, line UV, line WV, and line TW... then for the perimeter add all of the lengths, and for the area multiply the width and length

The area can be found with Width x Length

Perimeter can be found simply by counting the outer edge or doing (2 x Width) + ( 2 x Length)

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
