The diagrams (not drawn to scale) show a rectangular cardboard N and a square P. Reggie 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 Reggie could cut from a rectangular cardboard N?
(a)
Number of squares lengthwise
= 44 ÷ 5
= 8 r 4
Length of QR = 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
