The three sides make a right triangle and you know the base (90) and the height (70)
A = 1/2 bh or 1/2 x (70)x (90)= 3150 ft²
To find the area you do base times height. Base is the number across,and height is the number that is up and down.So in this case you will multiply 9 and 5 and 9 and 7 and get 45 and 72.Then you will add 45 and 72 together and get 117. So the area is 117. Answer 117. Hope this helps :D.
Answer:
The answer is x2 - 3x - 8.
Step-by-step explanation:
It’s only one day, so:
X - number of miles
Y- total cost for one day Enterprise
