The area of a triangular piece of stained glass is 50 square cm. if the height of the triangle is four times the base how long are the height and base of the piece of stained glass

The base is 5 as 5 x 20 = 100 and when solving the area of a triangle you divide by 2 to get 50. Hope this helps.

Work: A = h*b/2 
50 = 4b*b/2
50*2=100.
from there you use logical reasoning and can decipher that 20 x 5 = 100. 
Checking work:
5 x 4 = 20 making the height (20) 4 time greater than the base (5).

Idrk but i think u should figure out the n dia n then the units it will make it way more easier
