Answer:

70 - 5√10 ft²

Step-by-step explanation:

Perimeter is the distance around a two-dimensional shape.

area of rectangle: length x width

Here given:

length: (3√2 + 4√5) ft

width: (-5√2 + 5√5) ft

Solve for perimeter:

length x width

(3√2 + 4√5) x (-5√2 + 5√5)

apply distributive method

(3√2)(-5√2) + (3√2)(5√5) + (4√5)(-5√2) + (4√5)(5√5)

multiply

-15(2) + 15√10 -20√10 + 20(5)

combine

-30 -5√10 + 100

simplify

70 - 5√10
