Answer 1

Answer:

72 meter square

Step-by-step explanation:

area of 1st wall = area of 3rd wall

area of 2nd wall = area of 4th wall

area of 1st wall = l × b

                         = 7 m × 3 m

                         = 21 meter square

area of 1 st wall and 3 rd wall = 21 m + 21 m

                                                = 42 meter square

area of 2nd wall = l × b

                           = 5 m  × 3 m

                           = 15 meter square

area of 2 nd wall and 4 th wall = 15 m +15 m

                                                   = 30 m

area of 4 walls = 42 m + 30 m

                        =72 meter square
