W = width
4w = length

perimeter = 2(length) + 2(width)
perimeter = 2(4w) + 2w
perimeter = 8w + 2w
perimeter = 10w
90 = 10w
9 = w

length = 4w, 4(9) = 36. 
 
Length is 36 m. Width is 9 m.

The line graph below shows the number of chocolate bars and ice lollies sold at a small shop over a year
AnnyKZ [126]

Answer:

<em>The sales of ice lollies increased by 76 units between February and August</em>

Step-by-step explanation:

<u>Graph Reading</u>

Line graphs are visual ways of representing two or more data sets and their interrelation.

Graphs are pictures that show how one variable changes in relation to another.

Learning to properly read graphs is a matter of interpreting which pieces of information are useful.

The graph (in the red drawing) shows how sales of ice lollies changed in time. By February, the sales were about 4 units and by August sales were up to 80 units.

This means an increase of 80 - 4 = 76 units.

The sales of ice lollies increased by 76 units between February and August
