Answer 1

`\large\boxed{A=(223.3+49\pi)m^2}`

Explanation:

(look at the picture)

We have:

two halves of circle (whole circle) with radius r = 7m;

the suqare wih length side a = 14m;

the triangle with base b = 14m and hight h = 3.9m.

The formula of an area of a circle:

`A_1=\pi r^2`

Substitute:

`A_1=\pi(7^2)=49\pi\ m^2`

The formula of an area of a square:

`A_2=a^2`

Substitute:

`A_2=14^2=196\ m^2`

The formula of an area of a triangle:

`A_3=(bh)/(2)`

Substitute:

`A_3=((14)(3.9))/(2)=(7)(3.9)=27.3\ m^2`

The area of a figure:

`A=A_1+A_2+A_3\\\\A=49\pi+196+27.3=223.3+49\pi`
