Aschool wants to build a rectangular playground that will have a diagonal length of 75 yards. how wide can the playground be if the length has to be 30 yards?

We should use Pythagorean's theorem. a² + b² =c²  

Step-by-step explanation:

a² + b² = c²

75² = 30² + b²

5625 = 900 + b²

5625 - 900 = b²

4725 = b²

=

68.73863542 = b

b = 68.74

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

i think the correct option is the second option.
