Answer 1

Answer:

yes

Step-by-step explanation:

The cover is in the shape of a one face open cuboidal box.

l=20cm=0.2m,b=45cm=0.45m,h=50cm=0.5m

∴ Are of cloth required = L.S.A + area of the top

=2(l+b)h+lb

=2(0.2+0.45)0.5+(0.2×0.45)

=2×0.65×0.5+0.09

=0.65+0.09

=0.74sq.m

Given that cost of 1 sq. m of cloth is Rs 50

∴ cost of 0.74 sq. m of cloth is 50×0.74 =Rs37.
