Answer: 380 ft^2
Step-by-step explanation:
Length of sides of square=25
Diameter of semicircle=25
Radius=r=25/2=12.5
π=3.14
Area of square=length x length
Area of square=25 x 25=625
Area of semicircle=0.5 x π x r x r
Area of semicircle=0.5 x 3.14 x 12.5 x 12.5
Area of semicircle=245.3125
Area of shaded portion=area of square - area of semicircle
Area of shaded portion=625-245.3125
Area of shaded portion=379.6875
Area of shaded portion=380ft^2

In the case above, the side-side-angle (SSA) is no valid means for establishing triangle congruence.
<h3>What is the
triangle congruence about?</h3>
Using the image attached:
m angle A = M angle A
AB = A¹B¹
BC = B¹C¹
Looking at the image of both angles you will see that both are not congruence because Two triangles can be regarded as congruent if and when all its three corresponding angles or sides are said to be equal and all the three corresponding angles are also said to have equal measure.
