Question

Help me write a simplified expression for the perimeter of a square, please.

Answer 1

Perimeter of square = 12x² - 40

Explanation:

Perimeter of square formula,

→ P = 4 × Side

→ [ P = 4a ]

Now the perimeter of square is,

→ P = 4 × (3x² - 10)

→ P = 4(3x²) - 4(10)

→ P = (4 × 3)x² - 40

→ [ P = 12x² - 40 ]

Hence, perimeter is 12x² - 40.

Answer 2

12x² - 40

Explanation:

The perimeter of a two-dimensional shape is the distance all the way around the outside.

As a square has four sides of equal length, the perimeter of a square is four times the length of one side.

`\begin{aligned}\textsf{Perimeter}&=4(3x^2-10)\\&=4 \cdot 3x^2+4 \cdot (-10)\\&=12x^2-40\end{aligned}`
