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.
