The diagrams (not drawn to scale) show a rectangular cardboard M and a square N. Dylan cut as many squares N as he could from rectangular cardboard M. The remaining part of the rectangular cardboard M is shown in Figure 1.
- What is the length of PQ as shown in Figure 1?
- What is the greatest number of squares N that Dylan could cut from a rectangular cardboard M?
(a)
Number of squares lengthwise
= 44 ÷ 5
= 8 r 4
Length of PQ = 4 cm
(b)
Number of squares breadthwise
= 23 ÷ 5
= 4 r 3
Greatest number of squares
= 8 x 4
= 32
Answer(s): (a) 4 cm; (b) 32
