How to do this question plz answer me

x = 6 cm

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = bh ( b is the base and h the height )

Here b = 12 and h = 4, then

A = × 12 × 4 = 6 × 4 = 24 cm²

Then area of parallelogram = 3 × 24 = 72 cm²

The area (A) of a parallelogram is calculated as

A = bh ( b is the width and h the height )

Here b = x and h = 12, thus

12x = 72 ( divide both sides by 12 )

x = 6

The width of the parallelogram is 6 cm

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )
