and a w on its left side and right side.
Answer:
The greatest area of rectangle is:
625 square units.
Step-by-step explanation:
It is given that:
A rectangle of perimeter 100 units has the dimensions as:
50-w on the top and bottom.
and a w on its left side and right side.
i.e. we may say the length of the rectangle is:
50-w
and the width of the rectangle is:
w
Now, we need to find the greatest area of rectangle.
As the area of rectangle is:
A = w(50 - w)=50w-w^2
Now, to find the maximum area we differentiate the Area with respect to the width as:
Hence, to obtain the maximum area the width of the rectangle is: 25 units.
and that of the length of the rectangle is:
50-25=25 units.
Hence, the dimensions of rectangle in order to obtain the maximum area is:
25 units by 25 units.
So, the area of rectangle is:
Hence, the greatest area of rectangle is:
625 square units.

To answer this question, you have to find the circumference of the metal frame. The formula for the circumference of a circle is:
C = pi * d
So, you have to multiply pi which is 3.14 with the diameter
C = 3.14 * 14
If you do this the circumference of the circle will be 43.96 feet
C = 43.96

Answer: Right triangle.
Step-by-step explanation: The Pythagorean theorem can only be used in a right triangle and states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.
