You need to know the proportionality constant, or ratio of the two figures.
Suppose two corresponding sides have lengths of 10cm and 25cm, then the ratio is 25/10 = 2.5.
If another side of the first figure is 6cm long, then multiply it by 2.5 to find the length of the corresponding side: 6cm x 2.5 = 15cm.
If one side of the second figure is 30cm long, then divide it by 2.5 to get the length of the corresponding side in the first figure: 30cm / 2.5 = 12cm.
Surely you know how to find the third side of a right triangle, when you know the lengths of the other two. Find it, and then add up the lengths of the three sides to get the perimeter.
In order to find the perimeter of a 3D rectangle you must gather the lengths of the known sides, calculate the missing rectangular values, and use the formula for perimeter.
U can multiply
To find the missing measurement of a shape you have to look at the opposite side and see what it adds up to. Then you make that side and the other missing side add up to the opposite side
How do you find missed frequency if median and mode are given
You would look at the side lengths and the scale factor to find a pair of similar figures :)
You need to find the perimeter of one by adding together the lengths of all its sides. The perimeter of the similar shape is the answer multiplied by the similarity ratio.
If two objects have the same shape, they are called "similar." When two figures are similar, the ratios of the lengths of their corresponding sides are equal. To determine if the triangles shown are similar, compare their corresponding sides.
by multipling
Once you know the coordinates, you can use the distance formula to find the lengths of the sides, then using that, you can find the area.

It involves a right triangle. If a length is missing in a right triangle, you can find it out by using the other two lengths.
It all depends on what information you DO have. If all you have is two lengths, then all you can say is that the missing side is greater than the difference between the two and less than the sum of the two.
In order to find the perimeter of a 3D rectangle you must gather the lengths of the known sides, calculate the missing rectangular values, and use the formula for perimeter.
Assuming you are already sure that the two objects are, indeed, similar: You measure corresponding lengths of the two objects, and divide.You measure the lengths of a pair of corresponding sides. The scale factor is the ratio of the two measures.
The answer depends on what the problem is: are you required to find the lengths of the missing sides, the area, angles, length of diagonal, or WHAT!
