Answer:

[tex]5,811.95\ m^2[/tex] of fabric.

Step-by-step explanation:

-The amount of fabric needed is equivalent to the  area of the two gardens.

-We calculate the combined areas as:

[tex]A=A_s+A_b\\\\=\pi r^2+\pi R^2\\\\=\pi(25^2+35^2)\\\\=1850\pi \ m^2\\\\=5811.95\ m^2[/tex]

Hence, 5811.95 sq meters of fabric will be needed to cover the area of both gardens.
