Question

the top of a table measures 2 m 25 cm by 1 m 20 cm find the area of table cloth required, if a width of 1 m of cloth is left hanging on all four sides

Answer 1

length of table = 2m 25cm

then,
length of cloth = 2m 25cm + 1m
= 3m 25cm
= 3.25 m
and

breadth of table = 1m 20cm
then,
breadth of cloth = 1m 20cm + 1m
= 2m 20cm
= 2.20m

now, area of cloth is

area = length×breadth
= 3.25 × 2.20
= 7.15 m^2
$7.15 {m}^{2}$
