The area of a triangle is 80in^2. the ratio of the length of its base to its heights is 5: 2. what are the base and height of the triangle?

Data:
H (height) and B (base)
Area = 80 in²


Knowing that the formula of the area of a triangle:


Solving:
We isolate one of the terms (B or H) to find its values
Product of extremes equals product of means:


Now substitute in the formula the data found:












Now find the value of base (B), if:
