Answer:
H is 2.2cm.
Step-by-step explanation:
- A pentagon is a polygon with 5 sides.
- If all the sides are equal it is a regular polygon otherwise it is Irregular.
The Perimeter of the given pentagon =10.5cm
Four sides of Length Hcm are equal
The length of the fifth side = 1.7cm
Therefore: The sum of all the sides= 4H+1.7
4H+1.7=10.5
4H=10.5-1.7
4H=8.8
Divide both sides by 4
H=2.2 cm
The value of H is 2.2cm.
Answer: You would tell him 1,425ft².

First, you need to know the equation for finding the area of a trapezoid, which is <em><u>½</u></em><em><u>h</u></em><em><u>(</u></em><em><u>b1</u></em><em><u>+</u></em><em><u>b2</u></em><em><u>)</u></em> .
When you plug in all the number you have into the equation, you have a new equation essentially that says, <em><u>½×30(65+50)</u></em> .
When you start solving the equation, you need to do parentheses first, so <em><u>65+30</u></em>, which would get you 95. This would then turn the equation into <em><u>½×30(95)</u></em> .
Next, you have to do <em><u>30×95</u></em>, which would come out to be 2850. When you do this, your equation would now be <em><u>½</u></em><em><u>×</u></em><em><u>2</u></em><em><u>8</u></em><em><u>5</u></em><em><u>0</u></em> , or essentially <em><u>2850</u></em><em><u>÷</u></em><em><u>2</u></em> .
When you do the last and final step of the problem, which is <em><u>½×2850</u></em>, you would get 1425. But since it's area, your answer would <em><u>1425ft²</u></em>.
