The two triangles are similar. <span>When two </span>figures<span> are </span>similar<span>, the ratios of the lengths of their corresponding sides are equal. We use this fact in order to calculate the height of the bigger triangle. We do as follows:

QP / SL = MN / SL+SR
25 / SL = 35 / SL + 13
SL = 32.5

Area = height x base / 2
Area = SL x MN / 2
Area = 32.5 x 35 / 2 = 568.75

How do you explain how you convert a decimal?
Troyanec [42]
For example if we have 7/10 we have one 0 in the denominator so we move the decimal spot 1 to the left

So:
7.0 becomes 0.70 or .7

To make a decimal into a fraction:

0.32

Just add two zeros to the right and that means 2 0's will be added in the denominator
so:

0.32
32.0/100 or 32/100

Hope that helps :)
