We are interested in the dimensions of a certain square a rectangle had length triple the side of this square and width two unit
Sphinxa [80]

Let s be the side length of the square. The dimensions of the rectangle are three times the side of the square (i.e. 3s), and two less than the side of the square (i.e. s-2).

So, the area of this rectangle is

3s(s-2)=3s^2-6s

The area of the square is s^2, and we know that the two areas are the same, so we have

3s^2-6s=s^2 \iff 2s^2-6s=0 \iff 2s(s-3)=0 \iff s=0 \lor s=3

The solution s=0 would lead to the extreme case where the rectangle and the square are actually a point, so we accept the solution s=3.

Applying the midsegment theorem, the <u>value of x = 5</u>

<em><u>Recall:</u></em>

  • The midsegment theorem of a triangle states that the length of the mid-segment (DE) which is parallel to the third side (AC), is half the length of the third side AC of triangle BAC.

<em><u>Thus:</u></em>

DE = 1/2(AC)

  • Substitute

2x - 3 = 1/2(x + 9)

  • Multiply both sides by 2

2(2x - 3) = x + 9

4x - 6 = x + 9

  • Combine like terms

4x - x = 6 + 9

3x = 15

  • Divide both sides by 3

x = 5

Therefore, applying the midsegment theorem, the <u>value of x = 5</u>

<u></u>
