Answer 1

Step-by-step explanation:

For Wall,

Given; length= 6m

breadth=5.5m

A/q ; volume of wall = l×b

=(6×5.5)m²

= 33m²

Now, For Door,

Given;length=2m

breadth=1.5m

since,Volume of door =l×b

=(2×1.5)m²

=3m²

Now, For Window,

Given; length=1.2m

breadth=0.8m

since,volume of window= l×b

=(1.2×0.8)m²

=0.96m²

Now, the left side of wall= {volume of wall-(volume of door+volume of window)}

={33-(3+0.96)}m²

= {33-3.96} m²

= 29.04m²

The cost =₹29.04×80

=₹2323.2
