The length of the rectangular playground is 241.86 foot.
How to calculate length of the rectangle?Given that area of rectangle is 19,500 sq.ft and length of rectangle is three times its width.The area for rectangle is given by formula: A=LW.
Now according to the given condition, L= 3W. Further we'll solve by putting L= 3W in the formula for rectangle.
Calculation:A=LW
As given A= 19,500 sq.ft and considering L=3W,
19,500 = 3W*W
19,500 = 3W^2
∴ W^2 = 6500
∴ W = [tex]\sqrt{6500}[/tex]
∴ W = 80.6225 ft. ≈ 80.62 ft.
Now putting the value W = 80.62 in equation L =3W,
L = 3* 80.62
L = 241.86 ft.
The length of the rectangular playground is 241.86 foot.

The formula for the volume of a rectangular prism is V=l×w×h. Multiply the length times the width times the height to write a simplified expression in standard form to represent the volume of the box.
Answer:
Volume of box= Box Area * Box height
Step-by-step explanation:
If the box has equal sides then the l=w=h length is equal to height and both are equal to width so this can also be written as l=l=l or
Volume= length * width * height
V= l*w*h
V= l*l*l
V= l³
or if the three sides are not equal this can also be written as
Volume of box= Box length * Box width * Box height
If we observe closely we find that length * breadth gives the area so the volume of the box can also be written as
Volume of box= Box length * Box width * Box height
Volume of box= Box Area * Box height

Which function produces an output of 5 for an input of -6?
A.f(x) = x + 1
B.f(x) = 2x + 4
C.f(x) = x - (-1)
D.f(x) = -x - 1
Answer:
The answer is D
Step-by-step explanation:
Since the input is -6, you input it into the equation. That would make it f(-6)=-(-6)-1 which would be equivalent to f(-6)=6-1 , as the negatives at the beginning of the equation cancel each other out and make it positive. Then you solve and get 5, which is your output. Hope I could help :)
The area of the surface of a pool table is 24 square feet. The pool table is 6 feet long. How wide is it?
No procedure
Answer: The pool table is rectangle, so we assume it with Length a feet and b feet, respectively.
So area=a*b=24 square feet
perimeter=2(a+b)= 22 feet
then we calculate with this two equation to get a and b.
because a+b=11, then a=11-b, we put this into a * b=24
then we get (11-b)*b=24,
b^2-11b+24=0
b=3 feet or b=8 feet
then we can get a by a=11-b, if b=3, then a=8; if b=8, then a=3.
so the dimension of the pool table is 3 feet and 8 feet

B. 254.3
Step-by-step explanation:
The formula for the area of a circle is:
[tex]A = \pi\cdot r^2[/tex]
and r is half the diameter.
[tex]r = 18in / 2 = 9in\\~\\A = \pi \cdot (9in)^2 \approx 3.14 \cdot 81in^2 = 254.34in^2[/tex]
Answer:
D. 254.3
Step-by-step explanation:
Use the formula pi times the radius squared to get the area.
The radius is nine because the diameter of the diagram is 18. (The radius is always half the diameter).

Parveen buys 3 small bags of peanuts she gives the shopkeeper £2 and gets 80p change what is the cost of one pag of peanuts?
Answer:
$0.4
Step-by-step explanation:
Let cost per bag = x
Number of bags purchased = 3
Amount given to shopkeeper = $2
Change gotten = $0.80
(Cost per bag * number of bags purchased) + change obtained = amount given to shopkeeper
(x * 3) + 0.80 = 2
3x + 0.80 = 2
3x = 2 - 0.80
3x = 1.20
x = 1.20 / 3
x = 0.4
$0.4
