Step-by-step explanation:
has coordinates
and
Using the distance formula.........
Length of side
Length of side
Length of side
So, the perimeter of the triangle will be: units. <em>(Rounded to the nearest unit)</em>
The height of the triangle for the corresponding base is 8.89 units.
<u>Formula for the Area of triangle</u>,
So, the area of the will be:
square units. <em>(Rounded to the nearest unit)</em>
Answer:
Step-by-step explanation:
→ First understand what Pythagoras theorem is
Pythagoras is a theorem used to find the hypotenuse (the side opposite to the right-angle) of a triangle. We would need the base lengths as well the height in order to use Pythagoras.
→ State the formula and identify the letters
a² + b² = c² ⇒ where 'a' is 380cm, 'b' is 290cm and 'c' is what we are trying to work out
→ Substitute in the values into the formula
380² + 290² = c²
⇒ Simplify
144400 + 84100 = c²
⇒ Collect the numbers together
228500 = c²
⇒ Square root both sides to find 'c'
478.0167361 = c
→ The length of the diagonal is 478.02
