The area of the four wallsThe area of the roof​

Answer 1

Step-by-step explanation:

use formula 2 (l+b) h

2× 7+6×4= 104 ans

Answer 2

Here,

length=7m

breadth=6m

height=4m

(i)Area of the four walls:

=CSA of cuboid

=2h(l+b)

=2×4(7+6)

=8(13)

=104m²

(ii)Area of roof:

=Area of rectangle

=length×Breadth

=7×6

=42m²
