225, 9, and 49 are perfect squares. 
225 is a perfect square because 25*25 is 225
9 is a perfect square because 3*3 is 9
and 49 is a perfect square because 7*7 is 49

hope this helps!!

Each side of a square is increasing at a rate of 6 cm/s. At what rate (in cm2/s) is the area of the square increasing when the a
My name is Ann [436]

36 cm²s⁻¹ is the rate at which the area of the square is increasing.

Given each side of the square is increasing at a rate of 6cm/s

Area, A = s², s is the side length

=> \frac{dA}{dt} =\frac{dA}{ds}* \frac{ds}{dt} =2s*(\frac{ds}{dt} ) {chain rule of differentiation}

\frac{ds}{dt} = 6 cm/s

When A = 9 cm² => 9 = s²

=> s = √(9) => s = 3 cm

Hence, \frac{dA}{dt} = 2 × 3 × 6 = 36 cm²s⁻¹

Hence, 36 cm²s⁻¹ is the rate at which the area of the square increases
