Answer 2

Answer:

solution:

here,

length(l)=5m

breadth(b)=4m

height(h)=3m

area of four walls(A)=?

area of ceiling(a)=?

                  we know that,

area of four walls(A)=2*h(l+b)

                                   =2*3m(5m+4m)

                                   =6m*9m

                                   =54m^2

also,

area of ceiling(a)=l*b

                             =5m*4m

                             =20m^2

54m^2 is 54 meter square and 2om^2 is 20 meter square.Also * is the sign of multiplication.
