Length = x + 18

Width = x

Perimeter = 72

72 = 2(x + 18) + 2x

72 = 2x + 36 + 2x

72 = 4x + 36

72 - 36 = 4x

36 = 4x

36/4 = x

9 = x

The width is 9 feet.

The length is 9 + 18 or 27 feet.

Area = length • width

A = 27(9)

A = 243 ft^2

The rectangle below has an area of 14x^4+6x^214x 4 +6x 2 square meters. The width of the rectangle (in meters) is equal to the g

Answer:

Width = 2x² , Length = 7x² + 3

Step-by-step explanation:

The area of the rectangle = 14x⁴ + 6x²

The width of the rectangle (in meters) is equal to the greatest common monomial factor of 14x⁴ and 6x²

Factors of 14: 1 * 2 * 7

Factors of 6: 1 * 2 * *3

∴ The greatest common monomial factor of 14 and 6 = 2

Factors of x⁴: x , x² , x³ , x⁴

Factors of x²: x , x²

∴ The greatest common factor of x⁴ and x² = x²

∴ Width = 2x²

∵ Area = length times the width

∴ Length = Area/Width

Length = $\frac{14x^{4}+6x^2 }{2x^2} =\frac{2x^2*(7x^2+3)}{2x^2} =7x^2+3$
