K, well there is no surface area of a triangle, because a triangle is a 2s figure. Surface area is for a 3d figure. To find the regular area of a triangle the formula is 1/2 of the base X the height :) gl :P
Use the formula 1/2 the base * the height
If you know how to find the area of a triangle do the same thing and you will get the same answer.
area of a triangle is half the base times the height .5*22*28=308
Perimeter is the distance around the figure. Add all sides. Area depends on the figure. Triangle --- 1/2 bh Rectangle --- lw. Others --- divide into triangles and find the area of each triangle then add all together.
To calculate the area of a triangle - divide the length of the base by 2, then multiply that figure by the height. If the measurements are in centimetres, once you have your area - multiply your figure by 100 and you'll have the area in millimetres.

If the figure is a rectangle, the area is 60. If the figure is a triangle, the area is 30.
If the figure is a rectangle, the area is 60. If the figure is a triangle, the area is 30.
You don't have to do anything at all. As soon as you draw a triangle, it automaticallyhas area. The only trick for you is to figure out how much area it has.

The area is 0 square units since no shaded area is visible.

The area of a triangle does not provide enough information to determine its dimensions.
my idea is that to find the area of a 2 dimensional figure you have to multiply length *width which equal the area except a triangle and some other figure
