Dilate by 1/4 divide all the points
Triangle will be formed. base = 5-(-3)= 5+3=8 ( lies on the X axis ) height = 4 Area of triangle = base *height/2 =8*4/2= 16 sq. units
... I found this on Learn Pick btw
Diameter = Radius * 2
So radius of the circle is 25/2 = 12.5 feet
Area of a circle is:
A = πr² = 3.14 * 12.5² = 490 sq ft.
