Answer:
10.68 m
Step-by-step explanation:
Step 1: Area of flower bed
Uniform width means that all sides are the same which makes it a square.
Area of flowerbed = L²
Step 2: Area of rectangular lawn
Area of rectangular lawn = Length x width
Length = 8m
Width = 5m
Area of rectangular lawn = 8 x 5
Area of rectangular lawn = 40m
Step 3 : Calculate the width of the flower bed
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
