(i). What is the length of fence required?
(ii). What is cost of fencing the Garden? (iii). If length of garden is 20m and breadth10m then its area is…
(iv). Total perimeter of above garden is…. (v). formula used to find area of garden is …..​

Answer 1

Answer:

(i) Length of fence required = Sum of given three sides

                                              = 20 + 10 + 10

                                              = 40 m

(ii) Cost of fencing 1m = Rs 50

    Cost of fencing 40m = Rs 40* 50 = Rs 2000

(iii) Length = 20m

    Breadth = 10m

Area of garden = L*B = 20*10 = 200m

(iv) Total perimeter of above garden = Sum of given three sides

                                                             = 20 + 10 + 10

                                                             = 40 m

(v) Formula used to find area of garden = L*B
