Division is repeated subtraction, just like multiplication is repeated addition. If you divide 50 by 10, you get 5. This is also the question: How many times do you have to subtract 10 from 50 to get 0?

Triangle JKL has vertices J(−2, 2) , K(−3, −4) , and L(1, −2) .
Rule: (x, y)→(x + 8, y + 1 )
J’ (-2, 2) → (-2 + 8, 2 + 1 ) → (6, 3 )
K’ (-3, -4) → (-3 + 8, -4 + 1 ) → (5, -3 )
L’ (1, -2) → (1 + 8, -2 + 1 ) → (9, -1)
J’ (6,3)
K’ (5,-3)
L’ (9,-1)

Answer:
Use Heron's formula; see below.
Step-by-step explanation:
Use Heron's formula.
Let the sides of the triangle have lengths a, b, and c.
![s = \dfrac{a + b + c}{2}](https://tex.z-dn.net/?f=%20s%20%3D%20%5Cdfrac%7Ba%20%2B%20b%20%2B%20c%7D%7B2%7D%20)
![area = \sqrt{s(s - a)(s - b)(s - c)}](https://tex.z-dn.net/?f=%20area%20%3D%20%5Csqrt%7Bs%28s%20-%20a%29%28s%20-%20b%29%28s%20-%20c%29%7D%20)
Example:
A triangle has side lengths 3, 4, and 5 units.
Find the area of the triangle.
