<h3><em>Hope </em><em>it </em><em>helps</em></h3>
To solve this question, first cross multiply
Let ? = x
4/9 = x/81
4(81) = 9(x)
Simplify.
81 x 4 = 324
324 = 9x
Isolate the x, divide 9 from both sides
324/9 = 9x/9
x = 324/9
x = 36
4/9 = 36/81
36 is your answer
hope this helps!
Solving inequalities is almost the same as solving equalities for basic cases. Only thing you've to watch out for is signs.
For example, in 2x + 3 > 5,
We may subtract 3 from both sides,
2x > 2
Hence, by dividing both sides by 2, we get x>1.
The inequality sign changes on multiplying with (-)
For example, 2 < 6
But, -2 > -6
And when you interchange a fraction
E.g. 3/4 > 2/3
But, 4/3 < 3/2
You can now solve these of your own

Answer:
Step-by-step explanation:
1. Perimeter: 8cm + 8cm + 3cm + 3cm = 22cm
Area: 8cm x 3cm = 24cm
2. Perimeter: 5m + 5m + 5m + 5m = 20m
Area: 5m x 5m = 25m
3. Perimeter: 4m + 4m + 18m + 18m = 44m
Area: 4m x 18m = 72m
