The diagrams (not drawn to scale) show a rectangular cardboard V and a square W. Ethan cut as many squares W as he could from rectangular cardboard V. The remaining part of the rectangular cardboard V is shown in Figure 1.
- What is the length of XY as shown in Figure 1?
- What is the greatest number of squares W that Ethan could cut from a rectangular cardboard V?
(a)
Number of squares lengthwise
= 26 ÷ 3
= 8 r 2
Length of XY = 2 cm
(b)
Number of squares breadthwise
= 13 ÷ 3
= 4 r 1
Greatest number of squares
= 8 x 4
= 32
Answer(s): (a) 2 cm; (b) 32
