Ask the student a question, and give any hints about how they should answer this part.

Find the area of an equilateral triangle which has a side of $\var{side1}$ m.

{tri(side1)}

Unnamed gapm $^2$

Advice

Part1

where a=length of side

$\frac{\sqrt3}{4} \times \var{side1}^2= \var{ans1}m^2$

Or another method is:

A = $\frac{1}{2}$ ab $\sin(c)$ = $\frac{1}{2} \times \var{side1} \times \var{side1} \times \sin(60) = \var{ans1}m^2$

Formula for perpendicular height of triangle.

Area = $\frac{1}{2} \times$ base $\times$ perpendicular height

$2 \times \frac{\var{area2}}{\var{lent2}} = \var{ans2}m$

Give a worked solution to the whole question.
