The diagrams (not drawn to scale) show a rectangular cardboard Q and a square R. Asher cut as many squares R as he could from rectangular cardboard Q. The remaining part of the rectangular cardboard Q is shown in Figure 1.
- What is the length of ST as shown in Figure 1?
- What is the greatest number of squares R that Asher could cut from a rectangular cardboard Q?
(a)
Number of squares lengthwise
= 34 ÷ 5
= 6 r 4
Length of ST = 4 cm
(b)
Number of squares breadthwise
= 23 ÷ 5
= 4 r 3
Greatest number of squares
= 6 x 4
= 24
Answer(s): (a) 4 cm; (b) 24
