Answer:
4) C
5) C
Step-by-step explanation:
let, the height be h
area of the parallelogram= base x height
425 = 35 x h
425/35 = h
12.14m = h
question 9
a) 2 x 3 = 6m^2
b) diameter = 2m and radius = 1m
c) πr^2 is the equation, so 3.14 x 1^2 = 3.14m^2
and the semi circle is half of that, 1.57m^2
d) 6 + 1.57 = 7.57m^7
question 10
30 x 70 = 2,100m^2
πr^2 so 3.14 x 15^2 = 706.5m^2
2,100 + 706.5 = 2,806.5m^2
i hope this is correct :D
