A = L * W
A = 400
L = 4W
400 = 4W * W
400 = 4W^2
400/4 = W^2
100 = W^2
sqrt 100 = W
10 = W.....width is 10 cm
L = 4W
L = 4(10)
L = 40...length is 40 cm
P = 2(L + W)
P = 2(10 + 40)
P = 2(50)
P = 100 <=== perimeter is 100 cm
Answer:
true
Step-by-step explanation:
this is the decimal helps shorten up 29.600
Part 1 is all but Uranus.
Part 2, Are you sure it's 15:8? The ratio of all letter to consonants is 15:9 and all letter to vowels is 15:7.

Company A:
$200 + $2.99(30ft * 50ft) = $4,685
Company B:
30ft x 50 ft = 166.6667 sq yd.
$500 + $19.99(166.6667sq yd) = $3831.667
Company B is the better deal
