Answer: 32 meters
Explanation: The 4 meter pole casts a shadow of 5 meters. The towers unknown height casts a shadow of 40 meters. Now isolate the shadows. 5 and 40. 40 divided by 5 is 8, so 4 times 8 is 32.
w - width
2w - length
60 - perimeter
w + w + 2w + 2w = 6w - perimeter
The equation:
6w = 60 <em>divide both sides by 6</em>
w = 10 → 2w = 2 · 10 = 20
The area: A = width × length
A = (10)(20) = 200
<h3>Answer: The area of the garden is equal 200 square units.</h3>
87+87+81+86+89+83+89= 602. Divided by 7 because that’s how many numbers there were is 86 and that is your mean/average.
Given:
Base of a right triangle = 7 in
Height of a right triangle = a
Hypotenuse = 16 in
To find:
The length of side a.
Solution:
Using Pythagoras theorem:
Subtract 49 from both sides.
Taking square root on both sides, we get
a = 14.4
The length of side a is 14.4 in.
