The diagrams (not drawn to scale) show a rectangular cardboard R and a square S. Luis cut as many squares S as he could from rectangular cardboard R. The remaining part of the rectangular cardboard R is shown in Figure 1.
- What is the length of TU as shown in Figure 1?
- What is the greatest number of squares S that Luis could cut from a rectangular cardboard R?
(a)
Number of squares lengthwise
= 44 ÷ 5
= 8 r 4
Length of TU = 4 cm
(b)
Number of squares breadthwise
= 18 ÷ 5
= 3 r 3
Greatest number of squares
= 8 x 3
= 24
Answer(s): (a) 4 cm; (b) 24
