Answer 1

Answer:

13. a) The circle is divided into 8 parts.

     b) Perimeter = 48m

          Area = 143m²

Step-by-step explanation:

a) It says that all parts of the circle is 45º (equal measures). So, to find the total area of the path, we need to divide 360 by 45.

= $\frac{360}{45}$ = 8 parts

b) This is pretty easy. You just need to substitute the values in their respective formulae.

Perimeter of rectangle = 2 ( l + b)

Area of rectangle = l x b

Perimeter:    2 (l + b)  

                =   2 (13 + 11)

                = 2 x 24

                = 48m

Area: l x b

       = 13 x 11

        = 143m²       [In area, the unit becomes squared]
