Suppose a rectangular garden plot has a length that can be expressed as x+2 feet and a width expressed as x+7 feet. Write a poly

mafiozo [28]

Answer:

$Area = x^2 + 9x + 14$

$Perimeter = 4x + 18$

Step-by-step explanation:

Given:

Length of rectangular garden = (x + 2) ft

Width = (x + 7) ft

Required:

a. Polynomial expression of the area of the garden

b. Polynomial expression of the perimeter of the garden

SOLUTION:

Area of the rectangular garden = length × width

$Area = (x + 2)(x + 7)$

Expand using the distributive property of multiplication

$Area = x(x + 7) +2(x + 7)$

$Area = x^2 + 7x + 2x + 14$

$Area = x^2 + 9x + 14$

Perimeter = 2(length) + 2(width)

$Perimeter = 2(x + 2) + 2(x + 7)$

$Perimeter = 2x + 4 + 2x + 14$

Collect like terms

$Perimeter = 2x + 2x + 4 + 14$

$Perimeter = 4x + 18$
