The wall has a shape of trapezium, the area will therefore be given by:
A=1/2(a+b)*h
where a and b are the side length, h is height:
a=25, b=15, h=40
thus the area of the wall will be:
A=1/2(25+15)×40
A=1/2×40×40
A=800 ft²
Answer: Area=800 ft²

Actually Welcome to the Concept of the Circles.
The centre of the circle is given as, (h, k)
The equation in form of centre and radius of the circle is given as,
===> (x-h) ^2 + (y-k) ^2 = r^2
hence, the equation would be,
===> (x-90)^2 + (y-195)^2 = (88)^2
