Answer 1

`\huge\boxed{P\approx267.75m}`

Explanation:

Look at the picture in the attachment.

x it's the quarter of the circle with the radius r = 75m.

The formula of a circumference of a circle:

`C=2\pi r`

Therefore

`x=(1)/(4)\cdot2\pi r=(1)/(2)\pi r`

Substitute r = 75m:

`x=(1)/(2)\pi\cdot75=37.5\pi(m)`

The PERIMETER of the shaded region:

`P=2\cdot75+37.5\pi=(150+37.5\pi)m\\\\\pi\approx3.14`

substitute

`P\approx150+37.5\cdot3.14=150+117.75=267.75(m)`
