​

Answer 1

Answer:

where is image

first send the question correctly

Answer 2

Step-by-step explanation:

Area = 1/2 base × height

54 = 1/2 × base × 12

54 = base × 6 ( Transposing 6 To RHS side )

54/6 = base

9 = base

BC = √ 81 + 144

BC = √ 225

BC = 15 cm

Perimeter = 15+9+12

perimeter = 36 cm
