1. A piece of wood is cut as shown in Figure 4.51 below. The external and internal edge of the wood are similar quadrilaterals: 6m H 2 2cm b бm 15-4 А C G Figure 4.51 ie ABCD-FGHL. The lengths of the sides are indicated on the figure. How long are the internal edges marked as a, b, and C?

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
