The diagrams (not drawn to scale) show a rectangular cardboard N and a square P. Ken cut as many squares P as he could from rectangular cardboard N. The remaining part of the rectangular cardboard N is shown in Figure 1.
- What is the length of QR as shown in Figure 1?
- What is the greatest number of squares P that Ken could cut from a rectangular cardboard N?
(a)
Number of squares lengthwise
= 26 ÷ 3
= 8 r 2
Length of QR = 2 cm
(b)
Number of squares breadthwise
= 13 ÷ 3
= 4 r 1
Greatest number of squares
= 8 x 4
= 32
Answer(s): (a) 2 cm; (b) 32
