Answer 1

Here,

Base of parallelogram = 3 × Height of parallelogram

Base = 3 × Height.......(i)

So, Area of parallelogram = 867 cm²

867 cm² = base × height

867 cm² = 3 × Height × Height [Using (i)]

867cm² = 3 × Height ²

867/3 = Height ²

√289 cm² = Height

17 cm = Height

From (i), Base = 3 × Height

Base = 3 × 17

Base = 51 cm
