Question

Please please help!!!!!

Answer 1

`188√(2)-8√(5)` feet

Explanation:

Well the perimeter is the sum of all sides that means

P= lenght + width + lenght + width

P=2(lenght + width)

so

`P=2(2√(8)+3√(5)+45√(8)-7√(5) )\\\\P=2((2+45)√(8)+(3-7)√(5))\\\\P=2(47√(8)-4√(5))\\\\P=2(94√(2)-4√(5))\\\\P=188√(2)-8√(5)`
