Answer:
27 feet squared
Step-by-step explanation:
the formula for the area of a triangle is b(h)/2 so u just plug in the numbers into the formula from the question. we know that the base is 6ft long and the height is 9ft long.
A = b(h)/2
A = 6(9)/2
A = 27
therefore the area of the sail is 27 feet squared.
The formula for finding area of a rectangle is a=lw.
Write what is given
Area is 64.
Length if 16.
Width is unknown.
Therefore the equation would look like this:
64=16*w
Now to solve for w.
Divide 16 both sides.
64/16 is 4. Therefore:
w=4
The answer is (B) 7, 24, and 25
This is because 7 squared (49) plus 24 squared (576) makes 625, which is 25 squared. This is Pythagoras' theorem. I hope this helps!
