what would the height and base (3 times larger than height) be of a triangle with the area of 486

Question

the five D process and a shortened way to figure out the numbers that need to be multiplied by each other and divided by two to get the area of a triangle which is 486

Answer 1

Problem: what would the height and base (3 times larger than height) be of a triangle with the area of 486
the five D process and a shortened way to figure out the numbers that need to be multiplied by each other and divided by two to get the area of a triangle which is 486

1/2(h * 3h) = 486
1/2(3h^2) = 486   Multiply by 2 to eliminate the fraction
3h^2 = 972     Now, divide by 3
h^2 = 324
h = ±18

I believe we can ignore -18 as the height.

The height is 18, the base is 54.
