A rectangle is three times as long as it is wide. It’s perimeter is 36 units. Find the length of each side

Step-by-step explanation:

Let us say that the width is x

So this means that the legth is 3 times the width or 3x

Perimeter means to add up all the sides in the shape

So form an equation : 2(x)+2(3x)=36

And once you solve it you get x=36/8.

The width is 3(36/8) which is 13.5

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.

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)
