Answer:
what's the cost of the books then
Step-by-step explanation:
Answer:
The answer to your question is Area = 40 u²
Step-by-step explanation:
Data
A = (-1, -4)
B = (-1, 6)
C = (3, 6)
D = (3, - 4)
Process
1.- Plot the points to determine the base and the height (see the graph below)
2.- Calculate the distance between A and B and A and D
dAB = ![\sqrt{(-1 + 1)^{2} (-4 - 6)^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-1%20%2B%201%29%5E%7B2%7D%20%28-4%20-%206%29%5E%7B2%7D%7D)
dAB = ![\sqrt{0 - (10)^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B0%20-%20%2810%29%5E%7B2%7D%7D)
dAB = ![\sqrt{100}](https://tex.z-dn.net/?f=%5Csqrt%7B100%7D)
dAB = 10
dAD = ![\sqrt{(-1 - 3)^{2} + (-4 + 4)^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-1%20-%203%29%5E%7B2%7D%20%2B%20%28-4%20%2B%204%29%5E%7B2%7D%7D)
dAD = ![\sqrt{(-4)^{2} + (0)^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%28-4%29%5E%7B2%7D%20%2B%20%280%29%5E%7B2%7D%7D)
dAD = ![\sqrt{16}](https://tex.z-dn.net/?f=%5Csqrt%7B16%7D)
dAD = 4
3.- Calculate the area
Area = base x height
Area = 4 x 10
Area = 40 u²
0.20833333333any calculator can give you this answer
It would be 123,456,789 (if not counting decimals)
decimals would be like 0.123456789
