Answer :
Answer:Answer: (a) = P = 2(x + 2x-5) = 2(3x-5) = 6x - 10.
Step-by-step explanation:
Part a : Polynomial represents the perimeter of the garden is 6W-10
Part b : Polynomial represents the area of the garden is [tex]2w^{2}-5w[/tex]
Part c : Perimeter = 38 feet and area = 88 feet square
What is polynomial?
A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables
What is perimeter?
A perimeter is a closed path that encompasses, surrounds
What is area?
Area is the quantity that expresses the extent of a region on the plane or on a curved surface
Given,
Length is five less than two times the width
Consider
L is the length and W is the width
Then,
L=2W-5
Part a
Perimeter = 2(L+W)
Substitute the value of L
P=2(L+W)
P=2((2W-5)+W)
P=2(2W-5+W)
P=2(3W-5)
Perimeter= 6W-10
Part b
Area of the garden = L×W
Area = (2W-5)W
Area = [tex]2w^{2}-5w[/tex]
Part c
Given width W = 8 feet
Perimeter = 6W-10
P=6×8-10
Perimeter =38 feet
Area = [tex]2w^{2}-5w[/tex]
Area=[tex]2(8^{2})-5(8)[/tex]
Area = 88 feet square
Hence,
Part a : Polynomial represents the perimeter of the garden is 6W-10
Part b : Polynomial represents the area of the garden is [tex]2w^{2}-5w[/tex]
Part c : Perimeter = 38 feet and area = 88 feet square
