I think its... A (but not sure)
U count how many students were walking then multiply it by half itself
The answer would be the square root of 25 times 9 im pretty sure its been while and it would be 25*9=225 square root of 225 is 15
B. 16
if the length of each side is 16in, the total length would be 32in.
(16 x 2 = 32)
because the length is equal to twice the width, divide 32 by 2
(32/2 = 16)
16 + 32 = 48
