MNOP is similar to QRST with ratio of 5:4<span>. That means the MP:QT ratio would also be 5:4

The length of QT would be
</span>MP/QT = 5/4<span>
85mm/QT=5/4
85mm*4= 5*QT
5QT= 340
QT=68mm</span>

What is the area of the triangle?

Luda [366]

For this problem it would be...

30*18=540

540/2=270

So the area would be 270cm^2
