First since it is a triangle and it says meter square that means its an area
so the area is 1/2hb h stands for height and b stands for base
so
a=1/2bh
a=1/2(12)(9)
a=1/2(108)
a=54m^2
It says the cost of sail is $15 per square meter
so
$15*54
=$810
Why times by 54 because if 1 piece is $15 how about 54pcs?
thats why we will multiply it

Answer:
C
Step-by-step explanation:
Given that Q varies inversely as the square of p then the equation relating them is
Q = 
← k is the constant of variation
To find k use the condition Q = 36 when p = 7
k = Qp² = 36 × 7² = 36 × 49 = 1764
Q = 
← equation of variation
When p = 6, then
Q = 
= 
= 49 → C
A. Work. 16/cos(40)= 20.886
