The expression is the result of the perimeter of rectangle A and demonstrates the closure properly is Option (A) 14x+6; the answer is a polynomial.
What is perimeter of a figure ?
A perimeter of any geometric figure is denoted as the total space or the region occupied by the vertices of the given figure. Perimeter is a property applied to any geometric figure to characterize its shape and size.
How to calculate the perimeter of the given rectangle ?
Given that the length of the rectangle A is 4x + 5 and the width of the rectangle is 3x - 2.
The perimeter of rectangle is given by = 2*(length + width).
∴ Perimeter of rectangle A -
= 2*(4x + 5 + 3x - 2)
= 2*(7x + 3)
= 14x + 6
The given expression is a polynomial in variable x.
Thus the expression is the result of the perimeter of rectangle A and demonstrates the closure properly is Option (A) 14x+6; the answer is a polynomial.
