Answer:
40
Step-by-step explanation:
Surface area is the sum of the faces of all sides, so find the area of all sides and add
a. The area of the rectangle: 16 units²
b. The area of the triangle on the left: 6 units²
c. Area of the triangle on the right: 10 units²
d. Area of the figure: 32 units²
<h3>What is the Area of a Rectangle and a Triangle?</h3>
- Area of a rectangle = (l)(w)
- Area of a triangle = 1/2bh
a. l = 4 units
w = 4 units
Area of the rectangle = (4)(4) = 16 units²
b. b = 3 units
h = 4 units
Area of the triangle on the left = 1/2(3)(4) = 6 units²
c. b = 5 units
h = 4 units
Area of the triangle on the right = 1/2(5)(4) = 10 units²
d. Area of the figure = 16 + 6 + 10 = 32 units²

Answer:
√61 ≈ 7.81
Step-by-step explanation:
Distance formula:
√(x₂ - x₁)² + (y₂ - y₁)²
√(2 - (-4))² + (5 - 0)²
√(2 + 4)² + 5²
√6² + 5²
√36 + 25
√61
Answer: statement 2: a square is always a rhombus.
Step-by-step explanation:
A parallelogram does not have all the interior angle as right angle.
Therefore, it does not satisfy property of rectangle.
A square has all sides equal and its diagonals are perpendicular bisector.
Thus, square satisfies all the properties of rhombus .
A rectangle does not have all the sides are equal.
Therefore, it cannot b e a square.
