The side of triangle are 56cm ,60cm and 52cm then the area of triangle is ?

A=1344cm² √

Step-by-step explanation:

Using the formulas

A=√s(s﹣a)(s﹣b)(s﹣c)

s=a+b+c

2

Solving forA

A=1

1/4 √﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=1

1/4·√ ﹣564+2·(56·60)2+2·(56·52)2﹣604+2·(60·52)2﹣524

=1344cm²

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
