Answer:

<u>6ab + 8a² - 15b - 20a</u>

Step-by-step explanation:

Expand by using FOIL method

4(2a-5) + 3b(2a-5)

4a(2a) + 4a × -5 + 3b × -5

Simplify terms

8a² - 20a + 6ba -15b

<u>6ab + 8a² - 15b - 20a</u>

Answer:

A=2400ft

Step-by-step explanation:

A rectangle is a closed planer quadrilateral with four  right angles and its opposite sides are the same length. The fence around it including the gates is 200 feet long, so basically they are providing the perimeter of the rectangle. The perimeter of a rectangle is equal to the sum of all its sides. Hence:

Perimeter=w+h+w+h=2w+2h\\\\Where:\\\\w=Width\\h=Height

The ectangular playground is 40 feet wide, so:

w=40ft

Therefore:

Perimeter=2w+2h\\\\200=2(40)+2h\\\\200=80+2h

Solving for h:

2h=200-80\\\\2h=120\\\\h=\frac{120}{2} \\\\h=60ft

The area of a rectangle is equal to the product of two of its contiguous sides, hence:

A=wh\\\\A=(40)(60)=2400ft

I attached you a picture of the rectangle
