A rectangle is shown on the coordinate plane below. Complete the table below to determine which of the statements are true and which are false.

True False

A • The value of AB is 9.5 units.
B • The value of BC is 7.2 units.
C • The value of the perimeter is 33.4 units.
D • The value of the perimeter is 30 units.
E • The value of the area is 60 units.
F • The value of the area is 68.4 units.

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.
