Question

what is the perimeter of a quaduilateraleal whose four sides are 3 1/6 cm 2 3/4cm 4 5/12cm 2 1/2 cm​

Answer 1

Answer:

191/8

Step-by-step explanation:

Perimeter of quadrilateral = sum of all 4 sides.

Perimeter = (31/6 + 23/4 + 45/12 + 21/2) cm

" = { (31*3) + (23*6) + (45*2) + (21*12) }/ 24

.... {Since LCM of 6,4,2 & 12 = 24}

" = 93 + 138 + 90 + 252/24

" = 573/24

" = 191/8 Ans.

Answer 2

1. $3\frac{1}{6}$

⇒ The formula to find the perimeter of the quadrilateral = sum of the length of all the four sides.

∴ $3\frac{1}{6} \times 4$

that is

$3\frac{1}{6} \times \frac{4}{1}$

= $\frac{3\times6+1}{6}$ × $\frac{4}{1}$

= $\frac{19}{6}$ × $\frac{4}{1}$

=  $\frac{19\times4}{6\times1}$

= $\frac{76}{6}$

∴ The perimeter of the quadrilateral is $\frac{76}{6}$.
