10. The length of a rectangular field is 10m more than its breadth. If the perimeter is 80m, find its length and breadth.

b = 15m; l = 25m

Explanation:

let breadth of the field be x m

according to statement- length = (10+x)m

perimeter = 80m

therefore, 2(l + b) = 80

2(x+10+x) = 80

2(2x+10) = 80                                      

2x+10 = 40                                   (dividing both sides by 2)

2x = 40-10 = 30

therefore, x= 30/2 = 15m

hence, length = 15+10 = 25m

answer - breadth = 15m

length = 25m

compare & contrast informative essay/speech

when speaking or writing for the sole purpose of providing information in order to give audience members a good basis for making a decision, you would present an informative speech or essay.   because you wouldn’t want to be persuading the audience by arguing for one type of exercise over the other, you wouldn’t choose a persuasive/argumentative technique.   to fairly, and without bias, present information about the pros and cons of each type exercise, a compare/contrast, informative speech/essay would be the best bet.
