Answer:
81 square inches.
Step-by-step explanation:
Draw a diagram to represent what you know.
You don't know the values of the lengths so represent them algebraically.
You know the perimeter is 45 inches and that the perimeter is calculated by the sum of all of the sides of a shape.
You can rearrange to find the value of a side you've denoted as some unknown variable.
The area is given by the product of the sides. Express this algebraically and then input the value you found.
<h3>answer</h3>
we assume the height of the triangle is x,
so the base length will be x+4
the triangle area will be area = 1/2 ( base * height)
48 = 1/2 (x + 4) x
96 = x2 + 4x
96 + 4 = x2 + 4x + 4
100 = (x + 2)2
10 = x + 2 (for the square 100, we ignore the -10, minus is meaningless in length )
x = 8
x + 4 = 8 + 4 = 12
so the height for the triangle is 8 unit, base is 12 unit,

If this function is:
sin(cos(7/11))
Then it can not be evaluated without a calculator.
D is correct answer. X stands for adult tickets, y for children
