B = 2H - 3; (B x H)/2 = 10 ie B x H = 20;
2H2 - 3H - 20 = 0
(H - 4)(2H + 5) = 0
Only positive value for H is 4, making B = 5 cm
Its height is 8 inches
Height
It will be the base of the triangle
twice the area of the triangle with the same base an height.
The parallelogram has twice the area of the triangle if their bases are the same and their heights are the same. Area triangle = 1/2 base x height. Area parallelogram = base x height.
Its height is 8 inches

The parallelogram has twice the area of the triangle if their bases are the same and their heights are the same. Area triangle = 1/2 base x height. Area parallelogram = base x height.
It is base x height for the parallelogram. That is twice the area of a triangle which is: 1/2 base x height. (Base and height being the same for both cases).
47.88 cm2
If "length" means "length of side to which the height of 14 inches is perpendicular", area = (1/2)(14)(16) = 112 square inches. (These dimensionss of a triangle are more commonly called "base" and "altitude" respectively.)
You cannot determine the height from the information provided: more is required.
Area of a triangle = base * height / 2 Therefore the base = Area * 2 / height
lenght times width times height..
The formula for finding the area of a triangle is: Area = (base * height) / 2.
