A trapezoid has a perimeter of 14 feet. What will the perimeter be if each side length is increased by a factor 7?
A. 21 feet
B. 98 feet
C. 196 feet
D. 686 feet
This one is def B correct?
How will the area of the circle change if it is dilated by a scale factor of mc004-1.jpg?
correct.
To determine the new perimeter of the trapezoid when each side length is increased by a factor of 7, we first need to calculate the current perimeter of the trapezoid.
Let's assume that the trapezoid has side lengths a, b, c, and d. The perimeter is the sum of all four side lengths.
Based on the given information, the perimeter of the trapezoid is 14 feet.
Now, if we increase each side length by a factor of 7, we multiply each side length by 7.
The new perimeter will be:
new perimeter = (7a) + (7b) + (7c) + (7d)
Simplifying that equation, we get:
new perimeter = 7(a + b + c + d)
Since the current perimeter is 14 feet, we can substitute this value into the equation:
new perimeter = 7(14)
Calculating that, we find:
new perimeter = 98 feet
Therefore, the correct answer is B, 98 feet.
To find the new perimeter of the trapezoid after increasing each side length by a factor of 7, we need to multiply the original perimeter by 7.
The original perimeter is given as 14 feet. So, by multiplying 14 by 7, we get the new perimeter:
New perimeter = 14 * 7 = 98 feet.
Therefore, the correct answer is B. 98 feet.
