Question

(x + 1)
(x + 2)
(x + 2)
(2x + 2)
Perimeter of this is 77 cm.
​

Answer 1

$hi \: ...$

The sides of quadrilateral are

(x + 1) , (x + 2) , (x + 2) , (2x + 2)

Whose perimeter is 77cm

So..

$(x + 1) + (x + 2) + (x + 2) + \\ (2x + 2) = 77$

$x + 1 + x + 2 + x + 2 + \\ 2x + 2 = 77$

$5x + 7 = 77$

$5x = 77 - 7$

$5x = 70$

$x = \frac{70}{5}$

$x = 14$

Thus ,

The sides of quadrilateral are :

x + 1 = 14 + 1 = 15 cm

x + 2 = 14 + 2 = 16 cm

x + 2 = 14 + 2 = 16 cm

2x + 2 = 2(14) + 2 = 30 cm.
