The diagrams (not drawn to scale) show a rectangular cardboard S and a square T. Vincent 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 Vincent could cut from a rectangular cardboard S?
(a)
Number of squares lengthwise
= 23 ÷ 3
= 7 r 2
Length of UV = 2 cm
(b)
Number of squares breadthwise
= 13 ÷ 3
= 4 r 1
Greatest number of squares
= 7 x 4
= 28
Answer(s): (a) 2 cm; (b) 28
