The diagrams (not drawn to scale) show a rectangular cardboard E and a square F. Vaidev cut as many squares F as he could from rectangular cardboard E. The remaining part of the rectangular cardboard E is shown in Figure 1.
- What is the length of GH as shown in Figure 1?
- What is the greatest number of squares F that Vaidev could cut from a rectangular cardboard E?
(a)
Number of squares lengthwise
= 27 ÷ 4
= 6 r 3
Length of GH = 3 cm
(b)
Number of squares breadthwise
= 18 ÷ 4
= 4 r 2
Greatest number of squares
= 6 x 4
= 24
Answer(s): (a) 3 cm; (b) 24
