Answer:C 12hours
Step-by-step explanation:
the area and circumference ones are correct. a quadrilateral has 4 sides, so that one is incorrect. hope this helps!
I believe #2 would be the best answer. Either that or #1.
Answer:
52
Step-by-step explanation:
Given:
AB = 10, AD =24
Required:
Value of AC + BD
SOLUTION:
AC = BD (both are diagonals of the rectangle)
Use pythagorean theorem to find AC.
Thus:
AB² + AD² = BD²
Plug in the values
10² + 24² = BD²
676 = BD²
√676 = BD
26 = BD
BD = AC = 26
Therefore,
AC + BD = 26 + 26 = 52
Answer:

Step-by-step explanation:
A rectangle is a closed planer quadrilateral with four right angles and its opposite sides are the same length. The fence around it including the gates is 200 feet long, so basically they are providing the perimeter of the rectangle. The perimeter of a rectangle is equal to the sum of all its sides. Hence:

The ectangular playground is 40 feet wide, so:

Therefore:

Solving for h:

The area of a rectangle is equal to the product of two of its contiguous sides, hence:
