Answer:

a.ℓ=(P/2)-w, b.ℓ=18 cm

Step-by-step explanation:

Hello

I can help you with this one

Let

perimeter=2ℓ+2w

perimeter=48 cm

width=6 cm

Step one

a. Write the formula in terms of ℓ, it means that ℓ must be isolated

P=2ℓ+2w

subtract 2w in both sides

P-2w=2ℓ+2w-2w

P-2w=2ℓ

divide both sides by 2

(P-2w)/2=2ℓ/2

(P/2)-w=ℓ

ℓ=(P/2)-w

Step two

b.Substitute the clues you are given into the rearranged formula.

replace the values

ℓ=(P/2)-w

ℓ=(48 cm /2)-6 cm

ℓ=24 cm - 6 cm

ℓ=18 cm

Have a good day

If you need the geometry and trigonometry I'll post those.  Instead I found an answer at this link: http://jwilson.coe.uga.edu/EMAT6450/Class%20Projects/Scarpelli/Scarpelli_MathematicsBaseballActivity.....
The distance from home plate to the pitcher's mound is 60.5 feet and from home plate to second base is <span>127.28 feet.
Pitcher's Mound to 2nd base = </span><span> <span> <span> 66.78</span> </span>f</span>eet

Given those distances, we KNOW a 50 foot sprinkler will NOT reach home plate and second base from the pitcher's mound.

I didn't figure out the pitcher's mound to 1st or to 3rd, since the question is already answered.
