A paperweight in the shape of a rectangular pyramid is shown:
A right rectangular pyramid is shown.
If a cross section of the paperweight is cut perpendicular to the base but does not pass through the top vertex, which shape describes the cross section? (1 point)
Rectangle
Triangle
Trapezoid
Hexagon
The shape that describes the cross section of the paperweight is a triangle.
What is the area of a triangle that has a height of 12 feet and a base length of 6 feet? (1 point)
24 feet2
36 feet2
48 feet2
72 feet2
To find the area of a triangle, you use the formula:
Area = (1/2) * base * height
In this case, the base length is 6 feet and the height is 12 feet.
Area = (1/2) * 6 ft * 12 ft
= 3 ft * 12 ft
= 36 ft^2
Therefore, the area of the triangle is 36 square feet.
