Question 1

(b) Write the perimeter of each shape.

Solution

(a)

(b) (i) The given figure is a rectangle in which

Length = 14 cm

Breadth = 7 cm

∵ Perimeter of a rectangle = 2 x [Length + Breadth]

∴ Perimeter of the given figure = 2 x [14 cm + 7 cm]

= 2 x 21 cm

= 42 cm

(ii) The figure is a square housing its side as 7 cm.

∵ Perimeter of a square = 4 x side

∴ Perimeter of the given figure = 4 x 7 cm

= 28 cm.
