Question 3 Geeta bought 2/5 meter of lace and Shamim bought 3/4 meter of the same lace to put a complete border on a table cloth whose perimeter is 1 meter long. Find the total length of the lace they both have bought. Will the lace be sufficient to cover the whole border?Length of lace Geeta bought = 2/5 meter Length of lace Shamin bought = 3/4 meter Now, Total length of lace they have bough = 𝟐/𝟓 + 𝟑/𝟒 = (2 × 4 + 3 × 5 )/4 = (8 + 15)/20 = 𝟐𝟑/𝟐𝟎 Thus, total lace bought is 𝟐𝟑/𝟐𝟎 metre Now, our next question is Will the lace be sufficient to cover the whole border? Given perimeter of cloth is 1 meter So, we need to check if Length of lace > Perimeter Now, In 𝟐𝟑/𝟐𝟎 , since numerator is greater than denominator Thus, we can say 𝟐𝟑/𝟐𝟎>𝟏 Hence, the lace will be sufficient to cover the border
