The area of square A is 40ft^2 . The area of square B is 250% of the area of square A. What is the length of one side of square B?

Step-by-step explanation:

We are given the area of square A as 40 ft². Then we are told that the area of square B is 250% of A's area. The equation in words that we are going to be using is:

Area of square B = 2.5 × Area of square A where the word "is" is replaced by an equals sign, and the word "of" is replaced by a multiplication sign. We know that the area of A is 40, so:

Area of square B = 2.5(40) and

Area of square B = 100 ft²

The area formula for a square is A = s², so if the Area is 100:

100 = s² so

s = 10ft

really your just stupid if you don't know this

step-by-step explanation:

answer: 5 17/33 % (to the tenth)

step-by-step explanation:

he guessed: 34.5 pounds

actual weight is 32.7

there for he is off:

34.5 -32.7 = 1.8

32.7 is the 100%

1.8 represents %? of 32.7

therefore:

32.7   - 100%

1.8     -     x%

x= 1.8*100%/32.7% = 18*100%/327%

x=1800%/327%   = (5 165/327)%

to the tenth:

5 17/33 %
