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.

Answer:</h2>
The value of s is 23°
<h2>
Step-by-step explanation:</h2><h3>Known :</h3>
- VW = VY
- WX = s + 69
- XY = 4s
<h3>Asked :</h3>
<h3>Solution :</h3>
Since VW line and VY line has the same length, so the WX line and XY line should also have the same length.
4s = s + 69
4s - s = 69
3s = 69
s = 23°
<h3>Conclusion :</h3>
The value of s is 23°
Answer:
no guaranteed classification
Step-by-step explanation:
Both a rectangle and a parallelogram have two pairs of congruent sides. Because we don't know anything about the angles between these sides, it is not possible to establish which kind of figure is.
Answer:
78.6
Step-by-step explanation:
Area of circle = Pi*r^2
r=5
for pi use calculator or pi=3.142
area =Pi*r2=(3.142)*5^2=(3.142)*25=78.55 = 78.6 (1 decimal place which is same with tenth)
