Answer:
180-43=137....................
okay so you should know that the formula for a triangle is:
A=1/2×b×h
where b is breadth and h is height
A is area
so they already gave the area which is 16.2 and they already gave a side ( doesn't matter if it's b or h in this question)
so we put these into the equation of the area of a triangle
A=1/2×b×h
16.2=1/2 × 6 × h
then you will solve algebraically to get 5.4cm which is you answer
to check if correct you can always put in all numbers in equation and you should get 16.2cm
In this case it's correct ✌
Linear because there is a constant change (+3)
the operation:

Gives a square number.
<h3>
How to get a perfect square?</h3>
A perfect square is the product of a number and itself.
As you can see in the example, 16 is a square number. Then let's try to get 16.
To get 16 we can use the difference:
20 - 4
So the first therm needs to be equal to 20, and the second equal to 4.
To write 20 in scientific notation we have:

To write 4 in in scientific notation:

Then the operation:

Gives a square number.
