An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by it's property i² = −1. The square of an imaginary number bi is −b². For example, 5i is an imaginary number, and it's square is −25.
Answer:
180-140=50 180-90-50= 40 m=40
A = area of triangle + area of rectangular + half of the circle area
_________________________________
triangle area = 1/2 × base × height
triangle area = 1/2 × 3 × 5 = 15/2 = 7.50
☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆
rectangular area = length × width
rectangular area = 6 × 5 = 30
☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆
circle half area = 1/2 × pi × radius^2
circle half area = 1/2 × 3.14 × 3^2
circle half area = 1.57 × 9
circle half area = 14.13
_________________________________
A = 7.50 + 30 + 14.13
A = 51.63 m^2
To write in the mixed fraction you have to simply divide 8 and 4.
To right in the mixed number we need to know numerator, denominator and divisor.
So in your problem our divisor is 4,
so now lets divide it


So, now we have to write it as mixed number..
mixed number will be

Hope this helped you.. :)
