A trapezoid has a perimeter of 14 feet. What will the perimeter be if each side length is increased by a factor 7? 21 feet 98 fe

natka813 [3]

Answer:

Correct choice is B

Step-by-step explanation:

Let a, b, c and d be the trapezoid's sides lengths.

The perimeter of the trapezoid is the sum of all sides lengths, thus,

$a+b+c+d=14\ ft.$

If each side length is increased by a factor 7, then new sides have lengths 7a, 7b, 7c and 7d. The perimeter of new trapezoid is

$7a+7b+7c+7d.$

Use the distributive property for this expression:

$7a+7b+7c+7d=7(a+b+c+d).$

Since $a+b+c+d=14\ ft,$ then

$7a+7b+7c+7d=7(a+b+c+d)=7\cdot 14=98\ ft.$
