A farmer is creating a rectangular garden such that the length is four times the width. The
area of the garden is 2077 square feet. Write and solve an equation to determine the width
of the garden, to the nearest tenth of a foot.

Answers

Answer:

Width of the garden = 22.8 foot

Step-by-step explanation:

Area of the rectangular garden = 2077 square feet.

Let

Width of the garden = x

Length of the garden = 4x

Area of a rectangular garden = length × width

2077 = 4x * x

2077 = 4x²

x² = 2077/4

x² = 519.25

find the square root of both sides

x = √519.25

x = 22.787057730211

To the nearest tenth of a foot.

x = 22.8 foot

Width of the garden = 22.8 foot

gdghdhsxjsjsj

Step-by-step explanation:

jcjcjcjcjjcjcjcjcjc

Answer:

t is a regular hexagon of side 2′. So it can be divided into 6 triangles equal in all respects.The sum of all interior angle of hexagon =(n-2)*180 = (6–2)180 =720 deg. each interior angle =720/6 =120 deg.Side of the triangle divides this angle into two equal halves each = 60 deg.when two base angles of each triangle are 60 and 60 third angle will also become 60 making it as equilateral triangle. N ow the area of hexagon =6*the area of each equilateral triangle of base 2 ft.=6*1/2*2*h. h is the altitude of the triangle=2/2*tan 60 = rt3 =1.732 .NOW area of hexagon =6*1.732 = 10.392 sq.ft
