The width of a rectangle is 1 2 of its length. what are the sides of the rectangle if its perimeter is 63 in.?the width is in, the length is in

The length of the rectangle is 21 inches, the width of the rectangle is 10.5 inches

Step-by-step explanation:

Let x inches be the length of the rectangle, then the width of the rectangle is inches.

The perimeter of the rectangle is the sum of all sides' lengths:

Thus,

Hence, the length of the rectangle is 21 inches, the width of the rectangle is 10.5 inches.

c.   x=2.4cm

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.
