Answer 1

$\huge\blue{\boxed{\boxed{\mathcal{\bf\purple{♡}{\pink{Answer}\purple{♡}}}}}}$

Area of the poster = 2.5 ×2.5= 6.25

Area of the wall = 10.5 × 8.5 =

89.25=89.25-6.25=83.00 sq m

83 × 12 = Rs.996

Answer 2

Step-by-step explanation:

Given that:-

Dimension of wall=> Breadth =>8.5m , length =>10.5m

Dimension of.sq.poster=>2.5m

To find:-

cost of painting of remaining part of wall. .

Area of wall=l×b

Area =10.5×8.5

=>89.25m^2

Area of poster=>Side^2

=>(2.5)^2

=>6.25m^2

Area of remaining part=>Area of wall

-Area of poster

Area of remaining part=>89.25-6.25

=>83m^2

Cost of painting=>12/m^2

So,Total cost=>83×12

996Rs.

Hence total cost=996Rs
