Answer 1

(a) is 15

(b) is 30

75 divide by 15 times 90 divide by 15 is 30

Answer 2

Explanation:

Highest common factor of 75 and 90 will be the largest possible length of the square.

75 = 5 * 5 * 3

90 = 3 * 3 * 2 * 5

GCF = 5 * 3 = 15

Length of the side of square = 15 cm

b) Number of squares = Area of sheet ÷ Area of square

`= (75*90)/(15*15)\\\\= 5 * 6\\\\= 30`

Total number of square = 30
