Area=1/2bh=1/2x15x6.5=48.75 sq cm
The area of the triangle in square meters is (1/2 the length of the triangle's base, in meters) times (the length of the triangle's height, in meters).
Surface area = 2*(length*width + width+height + height*length) = 370.125 square units.
The first is clearly not a suitable triangle.
it depends on what shape it is. square: perimenter/4 is one side's length. triangle: perminter/3 rectangle: perimeter/height = length or perimeter/length = height
square root (3) * side length / 2
The square of the length of the base plus the square of the length of the height will equal the square of the length of the hypotenuse of your right triangle, per Pythagoras. Square the hypotenuse, subtract the square of the height, and then find the positive square root of that and you'll have the base of your right triangle.
The area of the triangle in square meters is (1/2 the length of the triangle's base, in meters) times (the length of the triangle's height, in meters).
To find the altitude or height of an equilateral triangle, take one-half of the length of a side of the triangle and multiple by "square root" of 3. So, if for example, the side has length 10, the height = 5 Square root of 3.
You do not indicate if the given area is the total area of the square and the triangle. Or whether they are equal values.
Call the length of the base s and the slant height of one triangle l SA = s2 + 2sl
The formula for the surface area of a circle is pi times the square of the radius. The formula for the surface area of a triangle is base times height, divided by 2. The formula for the surface area of a square or rectangle is length times width.
Surface area = 2*(length*width + width+height + height*length) = 370.125 square units.
7.5 square units
0.4330 times the length of a side (in square units of length)
