Let us set up some variabe:
Use the known information:
Now lets find the area
Area = (1/2) * b *h = (1/2) * h * (2h + 8)
Hope that helps!

Zelie planned for a square pool to have a side length of 28 ft but found that it needs to be 14 ft long to fit in her backyard. She found the change of scale below.
Which is Zelie’s error?
Zelie should have divided both numbers by 14.
Zelie should have written the ratio as 28/7.
Zelie should have written the ratio as 14/8.
Zelie should have subtracted 14 from both numbers.
Original length of pool = 28ft
If he found that it need to be 14ft longer then the actual measure = 14th
given equation is;
(28 - 7)/14 - 7 = 14/7
Scale constant = original length/actual length
Scale constant = 28/14
Scale constant = 2
Hence the scale constant is 2
According to the option, Zelei should have divided both numbers by 14.
Answer:
1.445 × 10³
Step-by-step explanation:
Standard form is a way of writing a small number or a large number easily.
We should give the final answer in standard form.
1) (1.7 × 10⁴) × (8.5 × 10⁻²)
We enter this directly into the calculator to obtain a solution.
= 1445
We write this in standard form we have :
1.445 × 10³
Hello, Oliveria. I am saddened to hear that you have started a whole rewrite of your plan for mathematics, but fear not; there are a couple of resources and websites that are always ready for you. For starters, visit websites that have at least 7th or 6th grade and up in benchmark mathematics content; this would be IXL, KhanAcademy, or even take some of the lesson tutorials from places like Symbolab and mathpoppa (<span>please, don't use the algebra calculator a lot. It will add more to your demise). Any how, you can always ask your guidance counselor at your school for help, or even your algebra teacher for some tutorials on certain topics. Always at least try to ask for help from your teacher or friends; even if you think they can't help much, it is always best to try
It seems that you have enough self direction and initiative to go on this route, now you just need the additional boosts :)</span><span />
Answer:
B) 18
Step-by-step explanation:
Perimeter = 2 + 2 + 1 + 2 + 1 + 2 + 1 + 4 + 1 + 2
= 4 + 3 + 3 + 5 + 3
= 7 + 8 + 3
= 10 + 8
= 18
<u>The correct option is (B) 18</u>
