Question

The area of a triangle varies directly with the width and the height of the triangle. If 6 is the area when width = 4 and height = 3, what is the area of the triangle if width is 6 and height is 4?​

Answer 1

Explanation:

Answer 2

9

Explanation:

To find out, we use the formula for direct variation:

A = kwh

Where A is the area, k is the constant of proportionality, w is the width, and h is the height.

From the information given, we can find k:

6 = k (4)(3)

6 = 12k

k = 0.5

So, the area when width is 6 and height is 4 is:

A = kwh = 0.5 (6)(4) = 9
