Question

A classroom is 11 m long , 8 m wide , and 5.5 m high . Find the sum of the area of the four walls and it's floor

Answer 1

Answer:

=297 sq.m

Step-by-step explanation:

Dimensions of a classroom=

l=11m

b=8m

h=5.5m

Area of 4 walls=LSA of classroom

=2h(l+b)

=2×5.5(11+8)

=2×5.5(19)

=11(19)

=209 sq.m

Area of 4 walls and it's floor=LSA+Area of floor

=209+(lb)

=209+(11×8)

=209+88

=297 sq.m
