<h3>
Answer: 320 square meters</h3>
===================================================
Explanation:
The scale factor 4 means the dimensions of the second rectangle are 4 times larger.
The width of 4 meters bumps up to 4*4 = 16 meters.
The length of 5 meters becomes 4*5 = 20 meters.
So a 4 by 5 rectangle is similar to a 16 by 20 rectangle.
The area of the second rectangle is therefore 16*20 = 320 square meters.
---------------
As an alternative, you can compute the area of the 4 by 5 rectangle to get 4*5 = 20. Then multiply this with 4^2 = 16 to get 16*20 = 320.
The 4^2 = 16 multiplier is the result of squaring the scale factor.
So if you know the dimensions have been multiplied by 4, then the area has been multiplied by 16.
Answer:
The radius of the circle required is 5 inches
Step-by-step explanation:
we know that
The diagonal of the square is the diameter of the circle
The length side of the square is half the apothem
Let
a ----> the apothem
r ---> the radius of the circle (half the diagonal of the square)
Applying the Pythagorean Theorem
we have
substitute
