PLEASE NO LINKS I LOST SO MANY POINTS

We will split the trapezoid into right angle triangle and rectangle

Traingle with base 3cm and height 10 - 6 = 4cm

Area of traingle

       =

Area of rectangle with sides 6cm and 3cm

       =

Therefore, area of the trapezoid

       =

Area of the semi circle with radius 3/2 = 1.5cm

        =

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
