Answer:
31.5 units^2
Step-by-step explanation:
This is a right triangle
The x dimension is from B to C
-4 to 3 is 7 units
The y dimension is from A to B
5 to -4 = 9 units
The area of a triangle is
A = 1/2 bh
A = 1/2 (7)(9)
= 31.5
Answer:
Step-by-step explanation:
We can write the following proportion:
We know that the original perimeter of the Pentagon is 921 feet. So, substitute 921 for "old perimeter."
We are going to use a scale of 3 cm = 307 feet. Since the 307 feet corresponds to the original perimeter, we are going to substitute 307 for "old scale factor" and 3 for "new scale factor."
This gives us:
So, to find our scaled perimeter, we just need to find x.
Cross multiply:
Divide both sides by 307:
In other words, the total perimeter of Sawyer's drawing will be 9cm.
And we're done!
