If a rectangular plot of land is 30mt by 20mt . what is the ration of its area and perimeter

Step-by-step explanation:

600mt^2 is the area. Area= length times width. 30 by 20. 30 times 20 is 600

100mt is the perimeter. 30 by 20. meaning that two sides are 30 and two sides are 20. 30 plus 30 plus 20 plus 20 is 100

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
