To find the area of a parallelogram, you use the area formula:
Area = Base * Height
Then, all you have to do is substitute in your known integers and solve. Therefore:
Area = 15 * 21 2/3
When we multiply these two numbers, we get
Area = 325 square yards or yards
Area = Base * Height
Then, all you have to do is substitute in your known integers and solve. Therefore:
Area = 15 * 21 2/3
When we multiply these two numbers, we get
Area = 325 square yards or yards
Using the distributive property is the correct first step.
Now, using the associative property of addition, you get
Simplify the right hand side:
Add 5 and
On the left side, use the associative property. On the right, commutativity and associativity:
Simplify.
Answer:
The regular polygon is a nonagon
Step-by-step explanation:
<u><em>The correct question is</em></u>
What is the name of the regular polygon that each interior angle measures 140ﾟ?
we know that
The formula to find the sum of the interior angles in a regular polygon is equal to
where
n is the number of sides of the regular polygon
a is the measure of each interior angle of the regular polygon
we have
substitute in the formula and solve for n
so
The regular polygon has 9 sides
therefore
The regular polygon is a nonagon
