Question

three sides are given a= 15 m ,b=11m, c ==6 m .find its area​

Answer 1

Answer:

20√2 m ^2

Step-by-step explanation:

Sides: a=15m, b=11m and c=6m

⇒P=15+11+6=32m

⇒Semi perimeter=S=

2

32

, S=16m

⇒Area= √s(s−a)(s−b)(s−c)

(Heron's formula)

⇒A=

16(16−15)(16−11)(16−6)

⇒A=

16×1×5×10

= √800

=20√2 m ^2
