Step-by-step explanation:
So I will use an example to try and show you how to do this.
If we have , we know that we don't have like denominators. We can change this by finding one. All we need to do is multiply our denominators. So in our example, that would be
. Our new denominator would be 6. So now we would have
which isn't the same as our old equation. That is because we haven't multiplied our top numbers yet. To do this, we need to multiply the top number by the opposite denominator like so,
.
So our first fraction was
We then multiplied the whole fraction by the opposite denominator

Step-by-step explanation:
<h2>We first find the area of a trapezium and rectangular face</h2><h2>Fourmula to find the are of a trapezium is:</h2><h3>Area=1/2*(B+b)*h</h3><h3> =1/2*3.7*1.9</h3><h3> =3.515m²</h3><h2 /><h2>Since every rectangular face is different we gotta find each of them</h2><h3>Area1=4.8*2.1</h3><h3> =10.08 m²</h3><h3>Area2=4.8*1.4=6.72m²</h3><h3>Area3=4.8*2.3=11.05m²</h3><h3>Area4=4.8*1.9=9.12m²</h3><h3 /><h3>Now we find the area of the whole prism</h3><h3>Area=3.515*2+10.08+6.72+11.05+9.12</h3><h3>Area=44m²</h3><h2>Sorry my wireless went down!!!</h2><h2>Hope this helps and you already know what I would like to get</h2>
