Find the perimeter of a rectangle with a length of

Luba_88 [7]

Answer:

$P = 8\sqrt{2} + 10 + 2\sqrt{6}$

Can only be simplified through calculator using decimal equivalents.

Step-by-step explanation:

The perimeter of a rectangle is the formula P=2l+2w. Here $l=4\sqrt{2}$ and $w=5+\sqrt{6}$ . So the perimeter is:

$P= 2l+2w\\P = 2(4\sqrt{2} ) + 2(5+\sqrt{6} )\\P = 8\sqrt{2} + 10 + 2\sqrt{6}$
