1.
The side lengths are in the ratio <span>11:16:24, so let them be
</span><span>11k, 16k, and 24k for some number k.
</span>11k+16k+24k=510
k(11+16+24)=510
51k=510
k=10
so the actual sides are 110, 160 and 240 feet.

There is a famous formula, called Heron's formula, which calculates the area of a triangle, given its sides a, b and c.
we first calculate the half perimeter, which we usually denote by u:
then the theorem states that the area A is as follows:

In our case:
feet squared
Answer:D 7,258.745 ft squared
