Step-by-step explanation:

Given are

Sides of the triangle measure 4 units, 6 units, and 7.21 units.

We need to compute the area of a circle whose circumference matches the triangle's perimeter.

The triangle's perimeter corresponds to the circle's circumference.

4 + 6 + 7.21 = 2πr, where r is the radius of the circle.

r = 2.73 units

Circle's area is:

$A=\pi r^2\\\\A=3.14\times (2.73)^2\\\\A=23.402\ \text{units}^2$

or

A = 24 square units

Thus, the circle’s area is 24 square units.
