To find the area of a triangle with the given sides a, b and c we use an expression,
Area =
Where,
By applying this formula area of the given triangle is 4.8 m².
Side lengths of the triangle are 2m, 4.8m and 5.2m
Therefore,
Now substitute these values in the formula,
Area =
=
= 4.8 m²
Therefore, area of the triangle with the given sides is 4.8 m².

Answer:
A) y = (x + 3)² + 4
B) y = (x - 3)² + 2
C) y = (x - 1)² - 5
Step-by-step explanation:
2 units UP means that the vertex will be shifted from (-3 , 2) to (-3, (2 + 2) or (-3, 4)
As the y = (x + 3)² will still be zero at x = -3, we just need to change the "+ 2" to
"+ 4" to shift the curve upward by 2
y = (x + 3)² + 4
When we want to shift the curve to the right, we want the vertex to move from (-3, 2) to (3, 2)
This means that the term in parenthesis must be zero with our desired x value
(3 + C)² = 0
3 + C = 0
C = -3
y = (x - 3)² + 2
4 units right and 7 units down mean that the vertex is desired at (1, -5)
(1 + C)² = 0
C = -1
y = (x - 1)² - 5
