Answer» ong>Step-by-step EXPLANATION: Given: the SIDES of a triangle are 3 cm, 5 cm and 4 cm. To find out: Area of triangle Solution:- The LENGTHS of the sides are a=3 cm, b=5 cm, c=4 cm. ∴s= 2 a+b+2
= 2 3+5+4
cm=6 cm We use the formula, Δ= s(s−a)(s−b)(s−c)
. ∴Δ= 6(6−3)(6−5)(6−4)
cm 2
= 6×3×1×2
sq.cm =6 sq.cm |
