Question

The diagonals of rhombus WXYZ intersect at point P. If WP = 4 and ZP = 3, find the perimeter of the rhombus.

Answer 1

check the picture below.

keep in mind that, in a rhombus, the diagonals meet a right-angles, thus P is at that junction, and that though slanted, all sides in a rhombus are the same length, so if WZ is that much, so are the other 3 sides.

and of course, the perimeter is all sides summed up.
