Answers
Answer:
Q8: 171, Q9:
Step-by-step explanation:
Q8:-
Given,
Total No. of books bought= 1539
No. of cartons required for 1539 books= 9
A/Q
No. of books in each carton = 1539÷ 9 = 171
Q9:-
Measurement of roll of lace = 50m = (50×100)cm = 5000cm
No. of rect. table clothes = 4
Length of the rectangular table cloth = 210cm
Breadth of the rectangular table cloth = 85cm
So,
Perimeter of the rectangular table = 2(l+b)
Perimeter = 2 (210+85)cm
= 2× 295cm
= 590cm
Since, there are four rectangular table
Therefore, Perimeter of all 4 rectangles = 590×4
= 2,360cm
Now A/Q,
Total length of the lace-perimeter of 4 rect. = Lace left
5000cm-2360cm= 2640cm
Thus, 2640 cm of the lace is left
