What is the area of Mr Green's garden that he will use for planting flowers?

To determine the area of Mr. Green's garden designated for planting flowers, you need to know the dimensions of the garden or the specific section he intends to use. If the garden is rectangular, you can calculate the area by multiplying the length by the width. If the garden has an irregular shape, you may need to divide it into simpler shapes and sum their areas. Please provide those dimensions for an accurate calculation.
