A rose garden is formed by joining a rectangle and a semicircle, as shown below. The rectangle is 20 m long and 13 m wide. If the gardener wants to build a fence around the garden, how many feet of fence are required? (Use the value 3.12 for pi, and do not round your answer. Be sure to include the correct unit in your answer.)

Step-by-step explanation:

So may questions.

π is generally closer to 3.14. Do you REALLY want to use 3.12?

Which side of the rectangle is the semicircle attached to and which portion of the semicircle contacts the rectangle?.

what diameter is the semicircle? could be anything

I will ASSUME the simplest two possibilities

1) The semicircle has a diameter of 20 m and the flat side joins the 20 m side of the rectangle

Circumference of a 20 m circle is 20π m. Half that amount is 10π m.

This must be added to two sides of 13 m and one of 20 m

20 + 2(13) + 10π = 46 + 10(3.14) = 77.4 m  (77.2 with your pi value)

The semicircle has a diameter of 13 m and the flat side joins the 13 m side of the rectangle

Circumference of a 13 m circle is 13π m. Half that amount is 6.5π m.

This must be added to two sides of 20 m and one of 13 m

13 + 2(20) + 6.5π = 53 + 6.5(3.14) = 73.41 m  (73.28 with your pi value)

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
