Answer: 10 units²
Step-by-step explanation:
We can divide the shape along the y-axis to get 2 separate triangles. If we find the area of each and add them up, we can get the total area of the figure.
We can get each triangle's area using the formula 
<h3>Left Triangle</h3>
base length - 4 units
height - 4 units


<h3>Right Triangle</h3>
base length - 2 units
height - 2 units



Total = 8 units² + 2 units² = 10 units²
Area = Length x Width
63 = 9 x width
Width= 63 ÷ 9 = 7 feet
Answer: 7 feet
This is what a rectangular prism looks like
Now for the definitions:
The perimeter is.... all of the lengths of sides added together.
The area is.... the sides all added together cubed
The volume...... the whole inside. (Think like it’s a shoe box and then you fill the shoe box up with water) that’s the volume
Since we are rounding to the nearest hundreds place in 222,977 the hundreds would be the 9. The seven behind it would make the number round up since the rule is 0-5 round down 6-9 round up. you round the 9 up to 10 so you add 1 to the next number since you cant have 222,1000. thats wrong . the answer is
223,000
