Q5. A rectangular plot is given for constructing a house, having a measurement of 40 m long and 15 m in the front. According to the laws, a minimum of 3 m, wide space should be left in the front and back each and 2 m wide space on each of other sides. Find the largest area where a house can be constructed.

Answer 1

Answer:

1. side = 30 m

    diagonal = 48 m

so , other diagonal = √30*2 - 24*2

                                 = √900 - 576

                                  = √324 = 18 m

so , area = 1/2 * 48*36

               = 864 m units

For 18 cows = 864 / 18

                     = 48 m units
