Your answer would be 31.5 (so 32 when rounded up)
For triangles you basically multiply them together, and the divide your answer by two.
A= 1/2 b x h
A= 1/2 7 x 9
A= 1/2 63
A= 31.5 (rounded up to 32)
I hope I helped and if you need more you could always ask me :)

Answer:
1st club- 15x +20 Rations- 10x +40 After 4 months the clubs cost the same of $80. The Rations would be a better choice for 6 months.
Step-by-step explanation: 15 would be x because it is per month and you would add a $20 fee each month. For Rations 10 would be x because it is per month and you would add a $40 fee. If you put 15x +20 = 10x +40 (first subtract 10x from both sides and then you would get 5x then subtract 40 -20 and get 20, divide that by 5x and x = 4). 15 times 6 + 20 = 110, while 10 times 6 + 40 = 100 so that means rations would be the better choice
