50 POINTS PLEASE EXPLAIN ANSWER A slice is made perpendicular to the base of a right rectangular pyramid through the vertex.
Elza [17]
Um, we see that the slice created the triangle, and the formula to find the area of the triangle:
1/2×B×h where B represent Base and h represent height.
In this case, Base=5 cm
Height=11 cm
A=1/2×11×5
A=5.5×5
A=27.5 square cm. As a result, the area of the resulting two-dimensional cross section is 27.5 square cm. Hope it help!
