Answer:
the ? is 3
Step-by-step explanation: the whole area of the angle is ten so minus three so it is three!
Well, for number three. You know that the length of the RECTANGULAR garden is 6.8 meters. Since it is a rectangle the garden will have 4 sides:two lengths and 2 widths. an easy way to find the width is to multiply the single length by 2, so 6.8 meters becomes 13.6. Then, you subtract that from the total perimeter, this leaves you with 7 meters. Those 7 meters are the sum of both width sides added together, so all you have to do is divide 7 by 2 to get 3.5 meters as your width. Before I go on do you understand how I got that number?

Answer with explanation:
Properties of Rectangle
1. Opposite sides are equal and parallel.
2. Diagonals are equal and bisect each other.
3. Adjacent Sides are Perpendicular to each other.
→If two lines are parallel their slopes are equal and if two Lines are perpendicular, their product of slopes is -1.
→A Rectangle is a Quadrilateral also.
→Adjacent sides are perpendicular ,so , their slopes can't be equal.Product of their slopes should be equal to ,-1.
⇒Slope of AB × Slope of BC = -1
⇒Also, Slope of AB × Slope of BC = -1
Slope of AB × Slope of AD = -1
⇒ Slope of AD × Slope of CD = -1
Slope of CB × Slope of CD = -1
Option B And Option C
are statement which proves that polygon ABCD is not a rectangle.
Answer:
y = 7
x = 12
Step-by-step explanation:
14x+7y=217, then 14x = 217 - 7y
14x+3y=189, then 14x = 189 - 3y
217 - 7y = 189 - 3y
add 7y to each side of the equation:
4y + 189 = 217
subtract 1890 from each side:
4y = 28
divide both sides by 4:
y = 7
14x + 3(7) = 189
subtract 21 from each side:
14x = 168
divide both sides by 14:
x = 12
