To solve this problem you must apply the proccedure shown below:
1. By definition, the opposite sides of a parallelogram are parallel and have equal length.
2. The figure attached shows that the opposite sides with equal length are:
3. Keeping this on mind, you have that the side <em>c</em> and <em>a</em> are equal and measure six centimeters.
4. To find the length of the other sides, you must apply the following formula for calculate the perimeter of a parallelogram:
4. If you solve for <em>b</em>, you will obtain the measure of <em>b </em>and<em> d:</em>
Therefore the answer is:
The lengths of the sides are: 6 cm, 6 cm, 9 cm and 9 cm.
Answer:
the dimension of the poster = 90 cm length and 60 cm width i.e 90 cm by 60 cm.
Step-by-step explanation:
From the given question.
Let p be the length of the of the printed material
Let q be the width of the of the printed material
Therefore pq = 2400 cm ²
q =
To find the dimensions of the poster; we have:
the length of the poster to be p+30 and the width to be
The area of the printed material can now be:
=
Let differentiate with respect to p; we have
Also;
For the smallest area
p² = 3600
p =√3600
p = 60
Since p = 60 ; replace p = 60 in the expression q = to solve for q;
q =
q =
q = 40
Thus; the printed material has the length of 60 cm and the width of 40cm
the length of the poster = p+30 = 60 +30 = 90 cm
the width of the poster = =
= 40 + 20 = 60
Hence; the dimension of the poster = 90 cm length and 60 cm width i.e 90 cm by 60 cm.
