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
=> {chain rule of differentiation}
= 6 cm/s
When A = 9 cm² => 9 = s²
=> s = √(9) => s = 3 cm
Hence, = 2 × 3 × 6 = 36 cm²s⁻¹
Hence, 36 cm²s⁻¹ is the rate at which the area of the square increases

C(-6,5) D (-3,1)
to find a distance between two points use the following formula:
d=√(x2-x1)²+(y2-y1)²
d=√-3-(-6)+(1-5)²
d=√(-3+6)²+(-4)²
d=√(3)²+16
d=√25
d=5
