339 + x = 510
x = 171
(133+206+171)/3 =
For this case we have the following equation:

To solve we follow the steps below:
We add similar terms from the left side of the equation:

We divide between 6 on both sides of the equation:

Finally, we have to:

Answer:

Change the numbers into improper fractions then subtract
Answer:
55 sq meters
Step-by-step explanation:
Area of big triangle 7x5=35/2
