The area of a triangle is given by the formula $A= \frac{1}{2}Bh$ , where B is the base and h is the height. We can rearrange this formula to solve for B.

$\dfrac{A}{ \frac{1}{2}h} = B\\ \\\\\dfrac{2A}{h} = B$ .

We plug in the given area, 640 square millimeters, and the given height, 32 millimeters.

$B= \dfrac{2(640)\ mm^2}{32 \ mm} = 40 \ mm$ .

40 mm is our final answer.

The point (20,5) implies that there are 20 small tables and 5 large tables.

Step-by-step explanation:

We have been given that a catering company is expecting 150 people to attend the wedding. There are two types of tables, ones which can fit 6 people and ones which can fit 10 people.

If there are x tables which can fit 6 people and there are y tables which can fit 10 people, we can express the total number of people that can fit on all available tables as: $6x+10y$ .
