<em>Answer,</em>

<em><u>A/ 84cm^2</u></em>

<em>Explanation,</em>

<em>Let's start off with the sqaure. </em>

<em>All four sides are</em><em> 6cm.</em><em> Therefore, </em><em>6 * 6 = 36.</em>

<em>Now, for the triangles.</em>

<em>The area for one triangle is, </em><em>12</em><em>. </em>

<em>We concluded this by, using the formula </em><em><u>h*b/2</u></em><em> .</em>

<em>6 * 4 / 2 = 12</em>

<em>Then we do, </em><em>12 * 4</em><em> because there are </em><em>4</em><em> triangles.</em>

<em>12 * 4 = 48</em>

<em>Lastly we do, </em><em>36 + 48</em><em> to get, </em><em>84cm^2</em>


<u><em>Hope this helps :-)</em></u>

For the square, 6 x 6 = 36^2cm and for each triangle you have to use the equation base x height divided by 2 so each triangle is equal to 12^2cm. 12 x 4 = 48 + 36 is a total of 84^2cm or A
