A rhombus has diagonals measuring 12 units and 16 units. What is the perimeter of the rhombus?

1 answer:

5 0

4 * side^2 = diagonal1 ^2 + diagonal2 ^2
4 * side^2 = 12^2 + 16^2
4 * side^2 = 144 + 256
4 * side^2 = 400
side^2 = 100
side = 10
So the perimeter = 4*10 = 40

You know how to compute the perimeter of a rectangle of length L and width W:

P = 2(L+W)

Here, you're asked to use the given algebraic expressions for length and width and simplify the result of putting those in the perimeter formula.

P = 2((5x-2) +(3x+1))

P = 2(8x -1)

P = 16x -2 . . . the perimeter of the rectangle
