Divide the land into 2 rectangles.

Length of rectangle A = 240 m

Width of rectangle A = 288 m

Area of rectangle A = length * breadth 

Area of rectangle A = 240 * 288

Area of rectangle A = 69120 m^2

Length of rectangle B = 96 m

Width of rectangle B = 48 m

Area of rectangle B = length * breadth 

Area of rectangle B = 96 * 48

Area of rectangle B = 4608 m^2

Total area of land =  Area of rectangle A + Area of rectangle B

Total area of land =  69120 + 4608

Total area of land =  73728 m^2

Area of land required for each giraffe = 500 m^2

Total number of giraffes that can be accommodated

=  Total area of land /  Area of land required for each giraffe

=  73728/500

= 147.456

≈ 147

So, the land can accommodate 147 giraffes.
