The diagrams (not drawn to scale) show a rectangular cardboard S and a square T. Fabian cut as many squares T as he could from rectangular cardboard S. The remaining part of the rectangular cardboard S is shown in Figure 1.
- What is the length of UV as shown in Figure 1?
- What is the greatest number of squares T that Fabian could cut from a rectangular cardboard S?
(a)
Number of squares lengthwise
= 31 ÷ 4
= 7 r 3
Length of UV = 3 cm
(b)
Number of squares breadthwise
= 18 ÷ 4
= 4 r 2
Greatest number of squares
= 7 x 4
= 28
Answer(s): (a) 3 cm; (b) 28
