I need help

i hope this is what you were looking for.

see attached graph

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

pls refer ro the top for answer

so the rectangle is 80cm (area)

now to find the area of a triangle.

base times height.

your answer is 96cm.
