- What is the length of LM as shown in Figure 1?
- What is the greatest number of squares K that John could cut from a rectangular cardboard J?
(a)
Number of squares lengthwise
= 34 ÷ 5
= 6 r 4
Length of LM = 4 cm
(b)
Number of squares breadthwise
= 18 ÷ 5
= 3 r 3
Greatest number of squares
= 6 x 3
= 18
Answer(s): (a) 4 cm; (b) 18
