- What is the length of HJ as shown in Figure 1?
- What is the greatest number of squares G that Ben could cut from a rectangular cardboard F?
(a)
Number of squares lengthwise
= 27 ÷ 4
= 6 r 3
Length of HJ = 3 cm
(b)
Number of squares breadthwise
= 18 ÷ 4
= 4 r 2
Greatest number of squares
= 6 x 4
= 24
Answer(s): (a) 3 cm; (b) 24
