Answer:

15200

Step-by-step explanation:

area of two wall = 7*4*2= 56

and area of two wall = 5*4*2 = 40

total area of four wall is 96 m2

area of two door = 2*3*2 =12

area of four windows =4*2*1=8

subtract the area of windows and doors from wall

it will be 96-20=76

cost will be 76*200=15200
