Alright this one is a bit tricky,
here are the numbers 3 5 6
If the height is 6 to figure out the base we have to do 5 times 6 which is 25
Now we add 3 to 25 we get 28
So To find the area we know to do base times Height , so we do
28 x 6b = 84 Therefore your answer is 84 cm

Answer:
Step-by-step explanation:
"a base 3cm greater than 5 times its height". This expression can be modelled as it follows
[tex]b=3+5h[/tex]
Where [tex]b[/tex] is the base and [tex]h[/tex] is the height.
The are of a triangle is defined as
[tex]A_{triangle}=\frac{bh}{2}[/tex]
Replacing the given expression, we have
[tex]A_{triangle}=\frac{bh}{2}\\A_{triangle}=\frac{(3+5h)h}{2}[/tex]
But, we know that [tex]h=6[/tex], then
[tex]A_{triangle}=\frac{(3+5h)h}{2}=\frac{(3+5(6))6}{2}=\frac{(3+30)6}{2}=\frac{33(6)}{2} \\A_{triangle}=99[/tex]
Therefore, the area is 99 square centimeters.
