Answer:
10.68 m
Step-by-step explanation:
<u>Step 1: Area of flower bed</u>
<em>Uniform width means that all sides are the same which makes it a square.</em>
Area of flowerbed = L²
<u>Step 2: Area of rectangular lawn</u>
Area of rectangular lawn = Length x width
Length = 8m
Width = 5m
Area of rectangular lawn = 8 x 5
Area of rectangular lawn = 40m
<u>Step 3 : Calculate the width of the flower bed</u>
Combined Area = 154 m²
Area of rectangular lawn + Area of flower bed = Combined Area
40 + L² = 154
L² = 154
L = √114
L = 10.68 m
Therefore, the width of the flower bed is 10.68 m
Answer:
Domain = [0 , +∞)
Step-by-step explanation:
since r is the radius of a circle
Then
r must be a positive number.
Then
r ≥ 0
NOTE : if r = 0 ,then the circle reduces to a point .
