The diagrams (not drawn to scale) show a rectangular cardboard D and a square E. Andy cut as many squares E as he could from rectangular cardboard D. The remaining part of the rectangular cardboard D is shown in Figure 1.
- What is the length of FG as shown in Figure 1?
- What is the greatest number of squares E that Andy could cut from a rectangular cardboard D?
(a)
Number of squares lengthwise
= 35 ÷ 4
= 8 r 3
Length of FG = 3 cm
(b)
Number of squares breadthwise
= 18 ÷ 4
= 4 r 2
Greatest number of squares
= 8 x 4
= 32
Answer(s): (a) 3 cm; (b) 32
