The area of the larger ttaingle is 12 cm squared
36,000.
40,000 - 4000 = 36,000
What is the task and how many hours does it take?
Your equation is 6/25 = d/30. to solve this equation we have to get d by itself! to do this, you have to multiply each side by 30 since d is being divided by thirty. d/30 x 30 = d, 6/25 x 30 = 7.2, or 7 2/10
therefore, d = 7.2
hope this helps!
