35 of a thread was used to tie a box. 14 cm was used for the thread knot.
- Find the length of the thread used.
- What was the original length of the thread?
(a)
Length of the thread used
= 12 x 2 + 11 x 2 + 9 x 4 + 14
= 96 cm
(b)
Original length of the thread = 5 u
Length used to tie the box = 3 u
3 u = 96 cm
1 u = 96 ÷ 3 = 32
Original length of the thread
= 5 u
= 32 x 5
= 160 cm
Answer(s): (a) 96 cm; (b) 160 cm
