You probably know that the area of any triangle is (1/2) x (base) x (height).
Take that formula, substitute (2x+3) in the place where it says "base", and
substitute (3x-1) in the place where it says "height". Then do the multiplication,
and you'll have a tidy expression for the area of your triangle.
Of course, it'll still have an "x" in it, as well as an "x2", but you should expect that.
If the base and the height both depend on the value of 'x', then naturally the area
must also depend on the value of 'x'.
area = .5 base x .5 height, so height = area/(.5base) = 3.2 meters
Area of a triangle = base * height / 2 Therefore the base = Area * 2 / height
That the area of a triangle = 0.5*base*height
base = (2*area)/height
It is found by: base = (area*2)/height
The area of triangle is : 100.0
The area of triangle is : 90.0
area = .5 base x .5 height, so height = area/(.5base) = 3.2 meters
It is: 24 square units
The area of a triangle is one half base times height. 1/2 Base Height = Area 1/2 Base 8 = 108 Base 8 = 216 Base = 27
triangle
A triangle.
The area of triangle is : 100.0
5 square feet
Area of a triangle = base * height / 2 Therefore the base = Area * 2 / height
15 square cm
To work out the area of a triangle, you use the equation, 1/2 base * height... So in this scenario, the area would be: (25m / 2) * 32m = 400m2
