Select the correct answer from each drop-down menu. The boundary of a park is shaped like a circle. The park has a rectangular playground in the center and two square flower beds, one on each side of the playground. The length of the playground is l and the width is w. The length of each side of the flower beds is a. Which two equivalent expressions represents the total fencing material required to surround the playground and flower beds? Assume that the playground and beds do not overlap.

The total fencing material required to fence the playground and both flower beds is [___] or [___].

First drop-down menu options:
2(l + w) + 2(4a)
2(l + w) + 4a
2(lw) + 2a
lw + 4a

Second drop-down menu options:
2l + 2w + 8a
2l + 2w + 4a
2lw + 2a
lw + 4a

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

your answer is b.

x = 33.9

y = 65.6
