Answer:
7.5 × 10^3 m^2
Explanation:
The garden described in this question takes the shape of a rectangle, which has a length of 1.5 x102 m and width/breadth of 0.5 x 102 m.
To calculate the area, we use the formula for calculating the area of a rectangle, which is;
Area = length (L) × width (w)
Area = 1.5 x102 m × 0.5 x 102 m
Area = 150 × 50
Area = 7500
This, the area of the garden is 7500m^2 or 7.5 × 10^3 m^2
