Question

The area of a rectangular plot is 330 and its breadth i as 15 m findthe length of the plot and the cost of fencing it at the rate of 8.50 per meter

Answer 1

given area= 330m²
breadth= 15m
length= area/breadth= 330/15= 22 m
perimeter= 2( l+b)
=2(22+15)
=2×37
=74m
cost of fencing= 74× 8.50=$629

Answer 2

Answer:

Hey I hope this is helpful

Step-by-step explanation:

Given- area= 330m

           Breadth=15m

Solution-

We know area= l X b

                330=lX15

         This means l= 22

Now for finding the cost of fencing we need to find perimeter so ......

Perimeter=2(l+b)

               = 74m

Cost of fencing= 74x8.50

                           =  629
