2.9 cm
1. 14 cm
4 16 cm
0.29 The total length of all sides of a rectangular park s 72 metres​

Answer 1

Answer:

2.9 cm I hope this is helpful for you

Answer 2

Length of AB is 14 cm.

Step 1: Find the value of x.

Give-  DC= $2x$ , DA= $(2x-5)$, CB= $(x+2)$ , AB= $(x+7)$

As we know that in parallelogram, adjacent sides are parallel and equal.

so, AB=DC and CB=DA.

so, AB=DC

= $x+7=2x$

$2x-x=7$

$x=7$ cm

Step 2: Find the length of AB.

AB=$(x+7)$

= $7+7$

= $14$ cm
