Question

A rectangle has perimeter 200 feet.

Answer 1

Answer:1. (200-2L)/2      2.L x (200-2L)/2=A

Step-by-step explanation:

Answer 2

Answer:

Part 1)

$W=100-L$

Part 2)

$A(L)=L(100-L)$

Step-by-step$W = 100-L$ explanation:

We are given a rectangle with a perimeter of 200 feet.

Part 1)

The formula for perimeter for a rectangle is:

$200=2(L+W)$

We can divide both sides by 2:

$100=L+W$

And subtracting L from both sides yields:

$W=100-L$

Part 2)

The area of a rectangle is given by:

$A(L)=LW$

Since we solved for W earlier:

$A(L)=L(100-L)$
