Area of rectangle: 15 x 7 = 105
area of semicircle: 1/2 (3.14r^2)
radius is half of diameter so it would be 7.5
1/2 (3.14(7.5)^2)
=1/2 (176.71)
=88.355
rounded is 88.4
we are given


we can multiply -1 on both sides of second equation


we can see that
both equations becomes same
so, they are coincident............Answer
