The length of a rectangle is 3 units shorter than one-third of the width, x. enter an expression in the box that represents the perimeter of the rectangle. note: use one variable and a fraction in the answer.

! i have absolutely no idea how to ^^^

Let

y----------> the length side of the rectangle

x-----------> the width side of the rectangle

we know that

the perimeter of the rectangle is equal to

--------> equation

--------> equation

substitute equation in equation

therefore

the answer is

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
