Math question ?

dividend ÷ divisor = quotient
Then, dividend = divisor × quotient

When quotient = divisor:
dividend = divisor²  or  dividend = quotient²

This is just to see if you understand the meaning of the words
Q = N/D
The quotient Q is the ratio of the dividend N to the divisor D.
We can also write this as dividend N = Q*D

When the quotient Q equals the divisor D, then the dividend
N = Q^2 = D^2

Then the dividend equals quotient times divisor or quotient squared or divisor squared
