The square of the larger side is equals to the sum of the squares of the smaller sides.

a. 6, 8, 10

$6^2 + 8^2 = 36 + 64 = 100 = 10^2$

The answer is yes.

$10^2 + 24^2 = 100 + 576 = 676 = 26^2$

So yes

d. 20, 21, 28

$20^2 + 21^2 = 400 + 441 = 841 \neq 28^2 = 784$

So no.

stiv31 [10]

If the rectangle has a fixed width of 300, it means that

$2(l+w)=300 \iff l+w=150 \iff w=150-l$

where $w$ and $l$ are width and length, respetively.

So given the length $l$ , the are would be

$l\times w = l\times (150-l)=-l^2+150l$
