We need to find the area of the rectangle, which is one of the two faces that are parallel to each other. To do this, we need to find the length and width of the rectangle.
The length of the rectangle is the same as the length of the triangle's base, which is 5cm.
To find the width of the rectangle, we need to look at one of the triangle's perpendicular sides. The width of the rectangle is the same as the height of the triangle, which is 4cm.
Therefore, the area of the slanted rectangle face is:
Area = length x width
Area = 5cm x 4cm
Area = 20cm²
So the area of the slanted rectangle face is 20cm².
What is the area of the slanted rectangle face of this triangular prism?
5cm 5cm 3cm 4cm
