306 sq. cm

Explanation:

When sides of a triangle are given, use Heron's formula to find the area of the triangle.

Area = sqrt(p(p-a)(p-b)(p-c)

Where, p = (a+b+c)/2

and, a, b, c are sides of the triangle.

Therefore, p = (51+37+20)/2 = 54 cm

and, Area = sqrt(54xx(54-51)xx(54-37)xx(54-20)

= sqrt(54xx3xx17xx34 = 306 sq. cm
