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

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).

A triangle and a parallelogram can have the same area if the base and height of the triangle are proportional to the base and height of the parallelogram. Specifically, the area of a triangle is given by ( \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} ), while the area of a parallelogram is ( \text{Area} = \text{base} \times \text{height} ). Therefore, if the base of the parallelogram is twice the base of the triangle and they share the same height, their areas will be equal.
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
Yes. Any triangle can be fitted twice into a rectangle having the same base length and vertical height as the triangle. Consequently, whilst the area of a rectangle = length x width ; the area of a triangle = 1/2 base x height. If we were using the same words this would be 1/2 length x width.
