# Find the perimeter of the rectangle and squares of the previous problems 6 (iii).

Answer :

6 (iii) A(3, 3), B(–3, 3), C(–3, –3), D(3, –3)

plot points A, B, C and D and join them as shown

As seen in the figure ABCD is a rectangle

Length = CD = CF + FD

= 3 + 3

= 6 cm

⇒ CD = 6 cm

Breadth = AD = AE + ED

= 3 + 3

= 6 cm

⇒ AD = 6 cm

Perimeter of rectangle ABCD = 2 × (length + breadth)

= 2 × (CD + AD)

= 2 × (6 + 6)

= 2 × 12

= 24 cm

Perimeter of rectangle ABCD = 24 cm
