Use the equation a^2 + b^2 = c^2.
225 + 1296 = c^2
1596 = c^2
Square root both
39 = c
Answer:
52.500 by 52.500 inches
Step-by-step explanation:
The rectangle with maximum area will be a square. Its side length will be 1/4 the perimeter, so is 210/4 = 52.5 inches.
The figure is a 52.500 inch square. The interval of optimization is <em>closed</em>.
_____
Side lengths are restricted to the interval 0 to 105 inches.
__
Any n-sided polygon with a given perimeter will have its maximum area when the polygon is regular. A regular 4-gon is a square.
Answer:
none of them
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = 0.5 × base × perpendicular height
Here the base is BC and perpendicular height is AD, hence
Area of ΔABC = 0.5 × BC × AD
Answer:
20 yards
Step-by-step explanation:
Since it is an isosceles triangle, a perpendicular from it's peak to the base bisects the base.
30/2=15
So using the Pythagorean theorem, hypotenuse^2=base^2+height^2
25^2=15^2+H^2
625=225+H^2
H^2=400
height=20 yards
