The opposite sides of a parallelogram have measures (2x+10) cin and (x+15)

xz_007 [3.2K]

Answer:

The measure of the sides is 20 cm.

Step-by-step explanation:

Opposite side of a parallelogram:

Opposite sides of a parallelogram are congruent, that is, they have the same measure.

Measures (2x+10) cm and (x+15) cm:

This means that:

$2x + 10 = x + 15$

$2x - x = 15 - 10$

$x = 5$

2x + 10 = 2*5 + 10 = 10 + 10 = 20

The measure of the sides is 20 cm.

In parallelogram LMNO,NO=10.2 and LO=14.7 what is the perimeter of parallelogram LMNO?

Shtirlitz [24]

In parallelogram LMNO, NO = 10.2, and LO = 14.7. The basic property of a parallelogram that the opposite sides in a parallelogram are equal; so, two sides are 10.2 (NO=LM=10.2), and two sizes are 14.7, = (LO=MN=14.7).
The perimeter of the parallelogram LMNO is:
P= 2NO + 2LO.
P= (2 x 10.2)+(2 x 14.7).
P= 20.4 + 29.4.

So, P= 49.8.
