Find the value of “x” for a square whose side is 3x + 2 and perimeter is 92 cm

92=3x + 2

We need to subtract 2 from both sides in order to make the equation simpler.

So, 2-2=0 and 92-2=90. Now you have:

90=3x

Divide both sides of the equation by 3, in order to isolate the "X."

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
