Let the length be x

Area = x²
Perimeter = 4x

<span>Area of a square is 3 times its perimeter
</span>⇒ x² = 3(4x)

x² = 3(4x)
x² = 12x
x² - 12x = 0
x(x - 12) = 0
x = 0 or x = 12

Since x cannot be zero, x = 12

Answer: The length is 12 units.

larisa [96]

Answer and Step-by-step explanation:

<em>116 b.</em>

2^{10} = 1024\\2^8 = 256\\\\1024 + 256 = 1280\\\\\\2^5 = 32\\2^3 = 8\\\\32 - 8 = 24

1280 × 24 = 30720

<u>30720 ÷ 60 = 512. 512 is the solution; the expression is divisible by 60.</u>

<em>116 c.</em>

16^3 = 4096\\8^3 = 512\\\\4096 - 512 = 3584\\\\\\4^3 = 64\\2^3 = 8\\\\64 + 8 = 72

3584 × 72 = 258048

<u>258048 ÷ 60 = 4096. 4096 is the solution; the expression is divisible by 63.</u>

<em>116 d.</em>

125^2 = 15625\\25^2 = 625\\\\15625 + 625 = 16250\\\\\\5^2 = 25\\\\25 - 1 = 24

16250 × 24 = 390000

<u>390,000 ÷ 39 = 10,000. 10,000 is the solution; the expression is divisible by 39.</u>
