Step-by-step explanation:
P = 2l + 2w --> w = 1/2·P - l = 1/2·42 - 15 = 6 feet
Considering the playground to be a square:
Perimeter = x + x + x + x
P = 4x
Area = x²
Px = 4x²
x² = Px/4
Area = Px/4
The fencing will be equal to the perimeter, with area 256 sq yd
256 = Px/4
P = 1024 / x
A constant is a value in a formula that does not change its value.
For example, in the formula:
PV = nRT
The constant is R.
It means that regardless of the value of the other variables, R will always remain the same.
R: universal constant of gases.
