Radhika bought 30 metres of cloth. Out of
this, three pieces of lengthe 5m 38cm,
8m 7cm and am 5cm were cut off.
What is the length of the remaining piece?

Answer 1

Total area = 30 m²

=> ar(First piece) + ar(second piece) + ar(third piece) = 30

=> (5 × 0.38) + (8 × 0.07) + (l × 0.05) = 30

=> 1.9 + 0.56 + 0.05l = 30

=> 2.46 + 0.05l = 30

=> l = (30 - 2.46)/0.05

=> l = 550.8

.°. l = 550.8 m
