The answer is A = P²/16
The perimeter P of a square is sum of its sides s: P = s + s + s + s = 4s
The area A of a square with side s is: A = s * s = s²
Step 1: Solve s from the formula for the perimeter.
Step 2: substitute s from the formula for the perimeter into the formula for the area.
Step 1:
P = 4s
s = P/4
Step 2:
A = s²
s = P/4
A = (P/4)²
A = P²/4²
A = P²/16
With cross multiplication you can find that they are the same. In both equations, x would be 100.
Answer:
I thinks they take 5 hours to meet each other
Answer: 25%
Step by step explanation:
1. Turn it into a fraction (5/20)
2. Turn the faction into a decimal by dividing the numerator (5) by the denominator (20). (5÷20=0.25)
3. Multiply the decimal (0.25) by 100, to convert it into a percentage. (0.25×100=25%)
