Find the perimeter of rhombus star

Step-by-step explanation:

Perimeter of the rhombus, STAR, is the sum of the length of all it's 4 sides.

The coordinates of its vertices are given as,

S(-1, 2)

T(2, 3)

A(3, 0)

R(0, -1)

Length of each side can be calculated using the distance formula given as

Find the length of each side ST, TA, AR, RS, using the above formula by plugging in the coordinate values (x, y) of each vertices.

S(-1, 2) => (x1, y1)

T(2, 3) => (x2, y2)

T(2, 3) => (x1, y1)

A(3, 0) => (x2, y2)

A(3, 0) => (x1, y1)

R(0, -1) => (x2, y2)

R(0, -1) => (x1, y1)

S(-1, 2) => (x2, y2)

1/800 is the right answer
