we can find its area by heron's formula....
s = a + b +c /2
=11 + 15 + 6 /2 = 16 cm
area = √s(s-a)(s-b)(s-c)
=√16 (16-11)(16-15)(16-6)
=√16 (5) (1) (10)
√16 × 50 = 4√50
=4 √ 2× 5 × 5
=4 × 5√2 = 20√2cm^2
HOPE IT HELPS U IF YEAH PLZ MARK IT AS BRAINLIEST♥️✌️

A=6
B=11
C=15

6+11+15÷2=32÷2=16
AREA=√s{s-a}{s-b}{s-c}
√16×10×5×1
√2×2×2×2×2×5×5
