I'm sorry, idk the first one but the second one is 220.88ft
Answer:
7 and 1/15
Step-by-step explanation:
4+2 then add two fifths with two thirds (convert them into a mixed number)
Write the mixed number as a sum of the whole number (6+1 1/15)
6+1 is 7
answer is 7 1/15
Answer:
See below
Step-by-step explanation:
L = length
W = 2 feet less than L = L-2
Area = L x W
20 = L * (L-2)
20 = L^2 - 2L
0 = L^2 - 2L - 20
Use Quadratic Formula a = 1 b = -2 c = -20
L = [-b ± sqrt(b^2-4ac) ]/2a
to calculate <u> L = 5.5826 ft then W = L-2 = 3.5826 ft </u>
The distance between the points is 5
