Question

Find the area of a triangle whose two sides are 6cm and 12cm and its perimeter is 32cm.​

Answer 1

Answer:

Area ≈35.78cm²

Step-by-step explanation:

given,

a = 6 cm

b = 12 cm

p = 32 cm

A=1/4 √[﹣P^4 + 4P^3 a + 4P^3 b﹣4(Pa)^2﹣12P^2 ab﹣4(Pb)^2 + 8Pa^2b + 8Pab^2]

= 1/4· √[﹣32^4 + 4× 32^3 × 6 + 4 × 32^3 × 12﹣4x(32x6)2﹣12×322×6×12﹣4×(32×12)×2 + 8×32×62×12 + 8×32×6×122 ]

≈35.77709cm²
