Question

Find the perimeter of the
square in the given figure.
Also, find the value of a.
(Hint Sides of a square is
equal in length.]​

Answer 1

Answer:

a = 11 cm and Perimeter = 100 cm

Step-by-step explanation:

All 4 sides of the square will be of equal lengths.

So, 3a - 8 = a + 14

⇒  3a - a = 14 + 8

⇒     2a   = 22

 ⇒      a   =  11 cm

∴The length of the square = a + 14 = 11 + 14 = 25 cm

Perimeter of the square = 4 * Length = 4 * 25 = 100 cm

Answer 2

Step-by-step explanation:

a=11cm

perimeter =100cm

3a-a=14+8

2a=22

(a=11)

The length of the square=11+14=25cm
