A rectangle and a square have the same perimeter. the rectangle is of length 6cm and has an area of 48cm², find the length of th
EleoNora [17]

<em>The length of the square​ that has the same perimeter as the rectangle is of length 6cm and area of 48cm² is 7cm</em>

<h2>Explanation:</h2>

Let's call:

A_{s}:Area \ of \ square \\ \\ A_{r}:Area \ of \ rectangle \\ \\ P_{s}:Perimeter \ of \ square \\ \\ P_{r}:Perimeter \ of \ rectangle

From the question, we know that:

  • <em>A rectangle and a square have the same perimeter.</em>

So:

P_{s}=P_{r}

Moreover:

  • <em>The rectangle is of length 6cm and has an area of 48cm²</em>

Accordingly:

For \ Rectangle: \\ \\ L:Length \\ W:Width \\ \\ A_{r}=L\times W \\ \\ 48=6W \\ \\ W=8

Also:

A_{s}=s^2 \\ \\ S:Side \ of \ square

From the statement of perimeters:

P_{s}=P_{r} \\ \\ \\ But: \\ \\ P_{s}=4s \\ \\ P_{r}=2W+2L \\ \\ \\ Then: \\ \\ 4s=2W+2L \\ \\ \\ But: \ W=8 \ and \ L=6 \\ \\ 4s=2(8)+2(6) \\ \\ 4s=16+12 \\ \\ 4s=28 \\ \\ \boxed{s=7cm}

Finally, <em>the length of the square​ that has the same perimeter as the rectangle is of length 6cm and area of 48cm² is 7cm</em>

Nookie1986 [14]
Answer: A) Copy the angle

When you are constructing triangles when given a Side, Angle, and Side (SAS), you should first copy one of the side. 

Then, you should copy the angle that is between the sides. (That is the answer to your question)

Finally, you will copy the last side. Then, you will have congruent triangles.
