Question

I do not know how to do this! Please help me!

This figure is made of part of a circle and part of a square. What are the perimeter and the area of the figure? Use paper if it helps you with your thinking.

Answer 1

`\qquad\qquad\huge\underline{\boxed{\sf Answer}}`

Perimeter of given figure is equal to :

Perimeter of square - side length + quarter Circumference of the circle

that is :

`\qquad \sf  \dashrightarrow \:(10 * 4) - (5 + 5) + (2 \pi r)/(4)`

`\qquad \sf  \dashrightarrow \:40- 10 + (3.14 * 5)/(2)`

`\qquad \sf  \dashrightarrow \:30+ (15.7)/(2)`

`\qquad \sf  \dashrightarrow \:30 + 7.85`

`\qquad \sf  \dashrightarrow \:37.85 \: \: units`

So, the required perimeter is 37.85 units
