Answer:
(½) × diagonal length × sum of the length of the perpendiculars drawn from the remaining two vertices.
Step-by-step explanation:
or you can solve for the area of the rectangle then the area of the triangle and add them together
Answer:
Step-by-step explanation:
Given parameters:
Dimensions of the equilateral triangle = 6.2cm
Unknown:
Perimeter = ?
Solution:
The perimeter of the triangle is the sum of all its sides;
Perimeter = 3(L) for an equilateral triangle;
Perimeter = 3(6.2) = 18.6cm
to the nearest mm = 19.0cm
Answer:
60.84 cm²
Step-by-step explanation:
The formula for the area of a square is:
A=s²
A=7.8²
A=60.84 cm²
Answer:
Step-by-step explanation:
We can add the same quantity to both sides of the equations, and still have an equivalent equation. Let's add to both sides, then sum like terms
(this is the rule that allows us to move items from one side do the other of the equal sign by changing its sign)
At this point we have a solution, let's replace it to verify
Answer:
0.0423333333 meters
Step-by-step explanation:
When you convert, you will receive the same result.
