The instructions arent fully clear which your teacher wants. I would ask them for further clarification. I'm sorry I'm not more helpful.
Area of triangle = 1/2 ABsinC
Since all sides are equal, it means it is an equilateral triangle
⇒All angles are 60°
Area of triangle = 1/2 ABsinC
Area of triangle = 1/2 (3.5)(3.5)sin(60°)
Area of triangle = 5.3 in²

Answer: the total amount of money that they wanted to raise is $2400
Step-by-step explanation:
Let x represent the total amount of money that Keelan and her friends want to raise.
After the first event they raise $240 which is 10% of the total amount they want to raise. The amount of money that raised after the first event is expressed as
10/100 × x = 0.1 × x = 0.1x
Therefore,
0.1x = 240
Dividing both sides of the equation by 0.1, it becomes
x = 240/0.1
x = $2400
