the area of the retangler piece of foil is 11 1/4 square inches its length is 4 1/2 inches what is the width of the foil?

The width of the foil = w = 2.5 inches

Step-by-step explanation:

We know that the Area of a rectangular piece:

Here:

Given that area of the rectangular piece of foil:

Area = A = 11 1/4 square inches

               = 45/4 square inches

               = 11.25 square inches  

Length = l = 4 1/2 inches

                 = 9/2 inches

                 = 4.5 inches

Using the Area formula

    inches

Thus, the width of the foil = w = 2.5 inches

∠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.
