The formula for the perimeter of a square is P = 4s, where s is the length of one of the four (4) congruent sides of the square.
The formula for the area of a square is A = s², and we're given that the area of a square, whose perimeter we're trying to find, is 36 sq. units; therefore, we have:
A = s²
36 sq. units = s²
√(36 sq. units) = √s²
6 units = s (Note: We used the positive square root (6) rather than the negative square root (-6) since you physically can't have a negative length!)
Therefore, ...
P = 4s
P = 4(6 units)
P = 24 units is the perimeter of a square whose area is 36 square units
1. The integer is +5000.
2. The integer is -4.
Solution:
To write an integer that represents the given situation:
1. A plane flies at an altitude of 5000 feet.
Here, the distance between ground and plane is mentioned.
Plane is above the ground. So, it is positive integer.
The integer is +5000.
2. A swimmer is 4 feet below the surface of the water.
Here, also mentioned the distance between surface of water to swimmer.
But, it is below the ground. So, it is negative integer.
The integer is -4.
B, 2 5/8.
2 and 5/8 times itself is 5 1/4, meaning its half of 5 1/4.
I'm sorry if I'm wrong but I think it is 47%
