Since the formula to find the area of a parallelogram is base times height (A=bh), and you have been given the area and base already, you can set up an equation. Let h=height in this formula. h x 3.4 = 25. Using this formula, to find the height, you would divide 25 by 3.4 and get approximately 7.35 inches. So, your height= 7.35in. Hope this helps!

Answer:

The missing variable for a parallelogram:

height (h) ≈ 7.35 in or

height(h) ≈ 18.67 cm

Step-by-step explanation:

Area of parallelogram is base times the height.

i.,e
A =b * h where A is the area , b is the base and h is the height of the parallelogram respectively.

Given: Area (A) = 25 square in. and breadth(b) = 3.4 in.

To find the height:

Apply parallelogram;


A = b * h

Substitute the value of A and b in above formula;


25 = 3.4 * h

Divide by 3.4 to both sides;


(25)/(3.4) = (3.4)/(3.4)h

Simplify:

7.35294118 in = h

or

h ≈ 7.35 in.

To find height in cm

Use 1 in = 2.54 cm

then, h =18.6764 ≈18.67 cm

Therefore, the height in inches is 7.35 in. (approx)

or the height in cm is; 18.67 cm (approx)
