1) Suppose that |a+b| + |b+c| + |c+a| = 20. What is the maximum possible value of |a-b|?

2) Suppose that |a - b| + |b - c| + |c - d| + ... + |m-n| + |n-o| + + |x - y| + |y - z| + |z - a| = 20. What is the maxim possible value of |a-n|?

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

14 x 10 5

step-by-step explanation:

10 5 = 100,000

14x10,000 = 140,000
