Answer 2

Answer:

56.88 cm²

Step-by-step explanation:

We can solve this using the midpoint theorem,

By midpoint theorem,

LM = 1/2QR = 9 cm

LN = 1/2PR = 13 cm

MN = 1/2PQ = 14 cm

now,

using heron's formula, in triangle LMN

semiperimeter = 14 +13 +9/2 = 18 cm

therefore, area of triangle LMN = root over 18(18-14)(18-13)(18-9) cm² = root over 18 × 4 × 5 × 9 cm² = 18 Root over10 cm² = 56.88 cm²
