The value of x when the triangle and the parallelogram have the same area is 6 units
<h3>The dimensions</h3>The dimension of the parallelogram is given as:
- Height = x
- Base = 4 + x
The dimension of the triangle is given as:
- Height = x
- Base = 20
The area of a shape is the amount of space it occupies
The area of the parallelogram is calculated as:
The area of the triangle is calculated as:
Both areas are equal.
So, we have:
Divide both sides by x
Subtract 4 from both sides
Hence, the value of x is 6 units
