Given - Length of the Rectangular Plot : 16 meters
Given - Width of the Rectangular Plot : 4 meters
We know that - Area of a Rectangle is given by : Length × Width
Area of the Rectangular plot = (16 × 4) m²
Area of the Rectangular plot = 64 m²
Given : Square plot and Rectangular plot have same Area
Area of Rectangular plot = Area of Square plot
Area of Square plot = 64 m²
We know that - Area of Square is given by : Side × Side
Side × Side = 64 m²
S² = 64 m²
S² = 8² m²
S = 8 m
Answer : One side of the Square Garden plot is 8 meter
