The perimeter of a square field is 6400m. Find the cost of reaping the field at Rs.35 per 100 sq. m.​

side= 6400/4

       =1600

therefore the area= 1600*1600

                                2560000

cost of reaping 100sq.m.=35

cost of reaping 1sq.m= 0.35

cost of reaping 2560000m sq=  2560000*0.35

                                                    = 906000

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

answer: b
