James completely covered a square poster board using 68.2 inches with an exponent of 2.of cardstock. Which measurement is closest to one side of the poster board in inches?
A) 34 in.
B) 8 in.
C) 6 in.
D) 30 in.

A. 34in

Step-by-step explanation:

If James completely covered a square poster board using 68.2 inches with an exponent of 2, the the total perimeter of the square will be;

P = 2(68.2) = 136.4in

Since the perimeter of a square is expressed as:

P = 4L

136.4 = 4L

L = 136.4/4

L = 34.1in

Hence the measurement of one side of the square poster is closest to 34in

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
