Step-by-step explanation:
Answer:
3 is the missing value
Step-by-step explanation:
Given

Required
Complete the blank
The model is not given; but the question can still be solved.
We have:

Add 8 to 4

Add 24 to 12

Divide both sides by 12

Rewrite as:

Hence, the blank will be completed with 3
<u>Answer</u>:
b = 4a
<u>Step-by-step explanation</u>:


<em>changing sides changes sign division to multiplication.</em>
Answer:
15. Area of parallelogram = bh
b = 9m
h = 4m
a = 9*4 = 36m^2
You can also use the rectangle property here.
a = l*b
l = 9
b = 6
a = 9*6 = 54 m^2
Though I would prefer the first one better.
16. Area of triangle = 1/2*bh
b = 17m
h = 3
a = 17*3/2 = 51/2 = 25.5m^2
18. Area of a trapezium = a+b/2*h (a and b are two parallel sides and h the height)
a = 15
b = 7
h = 15
a = 15+7/2*15 = 22/2*15 = 11*15 = 165m^2
19. Area of triangle = 1/2*bh
b = 24
h = 7
a = 24*7/2 = 168/2 = 84
