The diagrams (not drawn to scale) show a rectangular cardboard W and a square X. Valen cut as many squares X as he could from rectangular cardboard W. The remaining part of the rectangular cardboard W is shown in Figure 1.
- What is the length of YZ as shown in Figure 1?
- What is the greatest number of squares X that Valen could cut from a rectangular cardboard W?
(a)
Number of squares lengthwise
= 35 ÷ 4
= 8 r 3
Length of YZ = 3 cm
(b)
Number of squares breadthwise
= 14 ÷ 4
= 3 r 2
Greatest number of squares
= 8 x 3
= 24
Answer(s): (a) 3 cm; (b) 24
