Of all the rectangles with a perimeter of 100 feet, find the dimensions of the one with the largest area

1 answer:

6 0

P=2l+2w
100=2l+2w
divide both sides by 2
50=l+w

So what two numbers that have a sum of 50 have the largest product?

25*25=625 which makes for a large area, the largest

answer=l=25 w=25

Answer:

area = 22,272

Step-by-step explanation:

area = length * width

to calculate the width, we need the first segment using the pythagorean theorem

$87^{2} + x^{2} = 145^{2}$

$7569 + x^{2} = 21025$

$x^{2} = 13456$

$x = 116$

length = 116 + 140 = 256

area = 87 * 256 = 22,272
