26. i. -4, -3, -2, -1, 1, 2, 3

ii. -2, -1, 1, 2

Step-by-step explanation:

27. GIVEN :-

i. Lenght = 5cm

ii. Breadth=8cm

TO FIND:-

THE PERIMETER AND AREA.

SOLUTION:-

According to the lenght and breadth, it can be assumed that it is a rectangle.

i. Perimeter of rectangle = 2 ( l+b )

= 2 ( 5 + 8)

= 2 × 13

= 26cm

Therefore, the perimeter of the rectangle is 26cm.

ii. Area of rectangle = l × b

= 5 × 8

= 40cm²

Therefore, the area of the rectangle is 40cm² or 40 sq.cm.

28. GIVEN -

Side of the square = 8cm

TO FIND -

Area and perimeter of the square.

SOLUTION -

AREA = Side × Side

= 8 × 8

= 64 sq.cm or 64 cm²

The area of the square is 64 cm²

PERIMETER = Side × 4

= 8 × 4

= 32 cm

The perimeter of the square is 32 cm.
