Answer:

b = 56.67 m

Explanation:

It is given that,

Area of the triangular field is 255 m²

We need to find the base of the field if its height is 9 m.

The area of a triangle is given by :

[tex]A=\dfrac{1}{2}\times b\times h\\\\b=\dfrac{2A}{h}\\\\b=\dfrac{2\times 255}{9}\\\\b=56.67\ m[/tex]

So, the base of a triangle is 56.67 m.
