Answer:
Step-by-step explanation:
Given

Express as an exponential notation
Apply the following law of indices
This gives:
<em>The second complete is incomplete; However, I'll assume it is: 35 times 35</em>
Using the same law applied in (1) above:
You're welcome and don't mention it, beforehand.
There's so little to this problem, and it will do you so much
more good to work it out yourself, that I'm just going to
point you in the right direction and give you a little push:
The area of a triangle is half of the product of its base and height.
A = (1/2) (base) (height)
I know you know what the base and height are, because
you just told them to US.
Base = 7.5m = 750 cm
Height = 6 cm.
Write those numbers in the formula in place of the words:
<span> A = (1/2) (base) (height)</span>
A = (1/2) (750 cm) (6 cm) .
Do that multiplication, and you've got your area.
Don't forget to keep the units when you multiply,
so that the answer is in units of cm² .
The answer may be a big number, and you may want to
change it to meter² instead of cm², to make it a smaller
number.
If you do that, remember that
1 meter = 100 cm
1 meter² = (1 meter) · (1 meter)
= (100 cm) · (100 cm)
= 10,000 cm²
