Answer 1

Answer:

write area of the triangle

then according to it solve it

Answer 2

Step-by-step explanation:

perimeter = a + b + c

= 5 + 5 + 6

= 16 cm

semiperimeter = 16/2 = 8 cm

area =

$\sqrt{s(s - a)(s - b)(s - c)}$

$\sqrt{8 \times (8 - 5)(8 - 5)(8 - 6)}$

$\sqrt{8 \times 3 \times 3 \times 2}$

$\sqrt{ 2 \times 2 \times 2 \times 3 \times 3 \times 2}$

area = 2 x 2 x 3

= 12 cm cubic
