we know that for a parallelogram the opposite sides are of equal length

hence in pqrs

pq= rs

pr= qs

therefore as in figure

pq= 4x-1

rs = 3x +7

hence

4x-1 = 3x +7

on solving

x=8

Pq= 4(8) -1= 31 cm

as perimeter is = 74 = 2( pq +qs)

37= (pq +qs)

qs= 6 cm

Answer:

A. A line graph

Explanation:

You use line graphs to track changes over time. Line graphs are better when the changes are small. They are also more useful when you want to compare changes over the same period for more than one group, for example, plants exposed to music and a control group.

B is wrong. A pie chart is best for comparing parts of a whole.

C is wrong. You can use a bar graph to track changes over time, but small changes are harder to spot.

D is wrong. You use a timeline to mark important points in time, for example, when you are deciding the times when you must complete various stages of a project.

Which of the charts below do you think is more helpful in showing the change in plant height over time?
