How many circular discs, each of 4 cm radius, can be cut from the rectangular metal sheet with dimensions : (i) 75 cm and 48 cm (ii) 64 cm and 60 cm

(i) Given: Rectangular sheet dimensions: Length = 75 cm, Width = 48 cm Radius of each circular disc = 4 cm ⇒ Diameter of each disc = 2 × 4 = 8 cm Number of discs that fit along the length = = 9 discs Number of discs that fit along the width = = 6 discs Total number of discs = 9 x 6 = 54 Hence, total number of discs = 54. (ii) Given: Rectangular sheet dimensions: Length = 64 cm, Width = 60 cm Radius of each circular disc = 4 cm ⇒ Diameter of each disc = 2 × 4 = 8 cm Number of discs that fit along the length = = 8 discs Number of discs that fit along the width = = 7 discs (As we cannot take 7.5 discs) Total number of discs = 8 x 7 = 56 Hence, total number of discs = 56.

In a pentagon ABCDE, DP is drawn perpendicular to AB and is perpendicular to CE also at point Q. If AP = BP = 12 cm, EQ = CQ = 8 cm, DE = DC = 10 cm and DP = 18 cm, find the area of the pentagon ABCDE.
