"+" goes in the blank.

Polynomials with rational real coefficients have irrational or complex roots in conjugate pairs. A root with a positive irrational or imaginary part will be matched by a root with a negative irrational or imaginary part.

Ymorist [56]

Area of the middle rectangular section = length x width = 35 x 20 = 700 square cm.

The radius of the circular sections is 25 cm

Area of a full circle is pi x r^2 = 3.14 x 25^2 = 1962.5 square cm.

There are two quarter circles which is 1/2 of a circle. The area of those would be 1962.5/2 = 981.25 square cm.

Total area of the figure = 700 + 981.25 = 1681.25 square cm
