Juile planted a rectangular garden that is 20 feet long. She placed 56 feet of fencing around her garden. Draw and label a sketch of her garden what is the width of her garden? What is the area?

Step-by-step explanation:

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

She placed 56 feet of fencing around her garden. This means that the perimeter of the garden is 56 feet. If the length of the rectangular garden is 20 feet, i means that

2(20 + W) = 56

Dividing through by 2, it becomes

20 + W = 28

W = 28 - 20

W = 8 feet

The formula for determining the area of a rectangle is expressed as

Area = length × width

Therefore,

Area = 8 × 20 = 160 square feet

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.
