Answer:
Explanation:
area of square=64x²+96x+36=4[16x²+24x+9]
=4[16x²+12x+12x+9]
=4[4x(4x+3)+3(4x+3)]
=4(4x+3)(4x+3)
=4(4x+3)²
=[2(2x+3)]²
=(4x+6)²
side length=4x+6
=
36x^2+96x+64 = 9x^2 + 24x + 16 = (3x + 4)^2
\text {Area } = 36x^2+96x+64
\text {Area } = (3x + 4)^2
\text {Area} = \text{ length}^2
\text {Length} = 3x + 4
