Arectangular playground has a perimeter of 180 feet. if the width of the playground is 24 feet less than the length, what is the width, in feet, of the playground? show work.

lenght=57

width=33

Step-by-step explanation:

The perimeter of a rectangle is calculated using the formula

P=2(w+l) where P is the perimeter, w is the width and l is the length.

We know

P=180

lenght (l) = x (unknown value)

width (w)= x-24

Now we change these values in the formula

180=2((x-24)+x)

180=2(x-24+x)

180=2(2x-24)

180=4x-48

180+48=4x

228=4x

x=228/4

x=57

Therefore

P=180

w= x-24 =57-24 =33

l=57

To confirm:

P=2(w+l)=2(33+57)=2(90)=180

I hope you find this information useful and interesting! Good luck!

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
