Answer
Here the area and the width of the rectangular fence are given. We have to find length of the fence.
( diagram )
The area A of a rectangle is given by the formula A=lw where l is the length and w is the width.
Given that area is 500 square feet and width is 20 feet.
Substituting values in formula,
⇒500=l×20
⇒20/500
= 20/1×20
[ Dividing both sides by 20 ]
⇒l=25 feet
∴ length of rectangular fence is 25 feet.
Hence, the answer is 25.
Answer with explanation:
When a Number cube numbered from 1 to 6 is rolled once,
total possible outcome ={1,2,3,4,5,6}
Probability of each outcome that is ,
→So, each outcome has equal chance when a die is rolled 6 times.But in actual ,that is in experimental probability this seems impossible.
→When you are dealing with theoretical probability,we state that ,yes when a number cube is rolled six times each outcome has equal chance of coming.
→No, my friend is Incorrect,because here he is performing experiment in real life,there are chances that in next five trials ,number 5 only appears on the number cube,but when number of rolling of number cube becomes very high and higher, then probability of occurring of each number becomes same.
