circle question: 69.66

the other question: 66.8

Step-by-step explanation:

For the circle question:

the circle is inscribed in the square, so the diameter of the circle = side of the square

so we need to find the area of square and circle

then do this

square area - circle area

square area(side×side) = 324

circle area(pi×r^2)≈254.469

so shaded region = 69.66

the other question:

we need to find the area of triangle and the area of the rectangle and add them together

A of Triangle (1/2×base×hight) = 34.32

A of rectangle (width × length) = 31.92

add them, so the answer will be = 66.8
