Answer:

1)the dimensions of the roomL=6m,B=5m,H= 4marea of the four walls (A) = 2(L+B)H =2(6+5)4 =2*11*4 =88 sq m---(1)2) dimension of the doorl1=2m, b1 = 1marea

Answer 2

Answer:

1054

Step-by-step explanation:

Surface area of the class excluding the ceiling and floor-

2(6*5)+2(6*4)

=2(30)+2(24)

=60+48= 108 m²

Excluding the window and the door,

=108- (2+0.6)

=108- 2.6

=105.4m²

Cost= 105.4* 10

=1054
