Answer:
triangle C has the largest area.
Step-by-step explanation:
From the the three triangles A, B, C based on the area occupied by the triangles, it can be seen that triangle C occupies the largest area.
On the centimetre grid, let each box represent one unit. For triangle A, the base is 2 boxes (i.e 2 units) and the height is 3 units, For triangle B, the base is 2 units and the height is 3 units while for triangle C, the base is 3 units and the height is 3 unit. The area of a triangle is given by:
Area = 
For triangle A:
Area = = 
For triangle B:
Area = =
For triangle C:
Area = = 
Therefore, triangle C has the largest area.
Since point L is merely found on the line MN, ML and LN are considered to be line segments. So adding both line segments should add up to line MN's total length which is 31 units. We can use the given relations to create a mathematical equation as follows:
Given: MN = 31; ML = h - 15; LN = 2h - 8
MN = ML + LN
Substituting the given values:
31 = h - 15 + 2h - 8
31 = 3h - 23
It is necessary to solve for the value of h. To do this, we must isolate h and solve for it:
Adding 23 to both sides of the equation:
31 + 23 = 3h - 23 + 23
54 = 3h
h = 18
Substituting the value of h to the equation of LN we get the following:
LN = 2(18) - 8
LN = 36 - 8
LN = 28
Therefore the value of LN is 28.
150(number of tissues)*20(length of tissues) = 3000cm.(total length)
Then to convert it to meters...
1 meter = 100 cm.
3000 ÷ 100 = 30
So 30 meters of paper is needed.
Does that help?
