Hi there!

Find the perimeter using the formula:
P = 2l + 2w
It is given that the dimensions are 2.8 × 1.9 so plug these number into the equation:
P = 2(2.8) + 2(1.9)
P = 5.6 + 3.8
P = 9.4m

I believe the correct answer from the choices listed above is option D. The correct transformation of figure QRST to figure QꞌRꞌSꞌTꞌ would be a reflection across point R of pre-image. <span> It is basically a 'flip' of a shape over the line of </span>reflection<span>. Hope this answers the question.</span>
