Find the area of a triangle if the base (b) is 12 inches and the height (h) is 18 in.

1. Use the formula
A=(h*b)/2

2. Plot the numbers in
A=18*12/2 = 108

3. The answer
108 in^2

Area of a triangle = 1/2 × base×height
so put the values in this formula
Area=1/2×12×18
=6×18
=108inches^2

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
