Question

-Find the perimeter of Ali's dish.
-Find the area of Ali's dish.

Answer 1

Perimeter of square = 8x²

Area of square = 4x⁴

Explanation:

Framing expressions:

Perimeter of square:

Side = 2x²

`\boxed{\text{\bf Perimeter of square = 4 * side}}`

= 4 *2x²

In exponent multiplication, multiply the constant and the variables separately. 4*2 gives 8 and there is no variable other than x².

= 8x²

Area of square:

side = 2x²

`\boxed{\text{\bf Area of square = side * side}}`

`\sf = 2x^2*2x^2\\\\= 2*2 * x^(2+2)\\\\=4x^4`

In exponent multiplication, if bases are same, add the exponent.

Answer: Perimeter of square = 8x²

Area of square = 4x⁴
