Answer:
(40+2b)cm
Step-by-step explanation:
Complete question
Jimmy is putting up a fence around his rectangular garden. One side of the garden is 20 feet long, and b represents the width, How much fencing material will he need.
To get the amount of fencing material needed, we will find the perimeter of the fence
perimeter of the fence = 2(L+W)
L is the length
W is the width
Given
Length = 20feet
Width = b feet
perimeter of the fence = 2(20+b)
perimeter of the fence = 2(20) + 2b
perimeter of the fence = 40+2b cm
Hence the amount of material needed will be (40+2b)cm
1 3/5 x 2 3/4
= 8/5 x 11/4
= 22/5
= 4 2/5 (4 and 2/5)
Answer
C) 160 in^2
Step by step explanation
First, let's find the area of the rectangle.
Area of a rectangle = length x width
The area of the rectangle = 20 * 10
= 200 in^2
Now let's find the area of the triangle that is removed.
Area of a triangle = 1/2 base * height.
Here base = 10 and height = 8. Plug in these values into the formula, we get
Area of the triangle = 1/2 * 10*8
= 5* 8
The area of the triangle = 40 in^2
The area of the remaining figure = Area of the rectangle - area of the triangle
= 200 - 40
= 160 in^2
The answer is "160 in^2"
Thank you.
X^2-10x+16= 0
(x-8)(x-2)=0
x = 8 or 2
