Question

How to do this question plz answer me ​

Answer 1

Answer:

x = 6 cm

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = $\frac{1}{2}$ bh ( b is the base and h the height )

Here b = 12 and h = 4, then

A = $\frac{1}{2}$ × 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

Answer 2

Answer:

6=width

Step-by-step explanation:

Ok so when looking at the question it say that the area of the paraellagram is three times the area of the trianlgle.

-to find the area of a triangle you must use the equation A=1/2LxW would be 24

now once you have 24 you times it by 3 which is 72 (you do this because in the problem it says the paraellagram's area is three times the triangles area so 72 is the paraellagram's area.

now you divide 72 by the only other measurement given to you by the paraellagram which is 12 the length

after dividing the 2 you should get 6 which is the answer

you do this because by dividing 72 by 12 you get the other amount needed to make 72 which was the width

A=1/2(4)x12=24

24x3=7272/12=6
