Answer:

2.5+7.5+-10n+-20

Step-by-step explanation:

Multiply everything on the inside by the number on the outside and put it together with addition signs.

-2.5(-3+4n+8)

-2.5*-3=7.5

-2.5(7.5+4n+8)

-2.5*4= -10

-2.5(7.5+-10n+8)

-2.5*8=-20

-2.5+7.5+-10n+-20

The pool is 40 since half of the other rectangle is 50 which the 2 halfs equal 100 and we already know the top side measurement which is 40 and 2 sides of 40 equal 80 and there’s 20 left so this concludes that’s the sides are 10 and square sides are congruent to each other which concludes that’s the AREA is 40
