What is the area of a triangle having dimensions of 29 cm by 21 cm by 20 cm showing work?
Let the sides of the triangle be abc and their opposite angles be ABC
Angle C: (21^2 +20^2 -29^2)/(2*21*20) = 90 degrees by the cosine rule
Area: 0.5*21*20*sin(90 degrees) = 210 square cm by the area sine rule
Alternatively: 0.5*21*20 = 210 square cm because it is a right angle triangle

How do you measure the area of a rectangle missing a corner?
If you know the dimensions of the missing triangle, then compute the area from those dimensions, then subtract that answer from the area of the full rectangle.

A right angle triangle fits the dimensions given
What is the area of triangle A B C if a 7 c 11 and B 100?
There is no such triangle with the given dimensions because to construct a triangle the sum of its two smaller sides must be greater than its longest side. But the area of any triangle is: 0.5*base*perpenducular height
How is the area triangle related to the area of a rectangle?
two right triangles = full rectangle That is - if you multiply height times base of a triangle, the area will be 1/2 of a rectangle having the same height, and a width the same as the triangle base.

Does an obtuse triangle have a greater area than an acute triangle?
It can have the same area, a greater area or a less area all depending on the dimensions of their 3 sides.
What is the area and perimeter of a triangle if its dimensions are doubled?
Area is quadrupled (*4) and perimeter is doubled.

If both dimensions are doubled then the area is quadrupled. This is true of any geometric shape.
