plzz can anyone answer the question fast

Answer 1

Answers:

a)175m^2

b)35m^2

c)27.712m^2

Step-by-step explanations:

a)

Area of outer fig.-area of inner fig.

={(20×30)-(5*5)}m^2

={600-25}m^2

=175m^2

Therefore,area of the shaded figure=175m^2

b)

Area of outer fig.-area of inner fig.

={(7*25)-(7*20)}m^2

={175-140}m^2

=35m^2

Therefore,area of the shaded figure=35m^2

c)Area=square root of 3/4*side^2

=(1.732/4*8^2)m^2

=(6.928*64)m^2

=27.712m^2

Therefore required area=27.712m^2
