Answer:

32 questions

Step-by-step explanation:

Well since there were 40 questions each question is worth 2.5 points.

How I got that? You divide 100 by 40 which you will get 2.5 because 100% is the maximum points you can get

Since each question is 2.5 points I multiply by 32 which it gave me 80

Hope this helps!!!

The area of a playground is 320 yards squared. The width of the playground is 4 yards longer than its length. Find the perimeter
Naddik [55]
The formula to find the perimeter of a rectangle is P = 2(l + w), where p is perimeter, l is length and w is width,

The length of the playground is 16 yards, and the width is 20, because 16 x 20 = 320 and 16 + 4 = 20.

P = 2(l + w)
P = 2(16 + 20)
P = 2(36)
P = 72.

The perimeter is 72 yards.

Hope this helps!!
