check the picture below.
recall that in a rhombus, both diagonals bisect each other, namely cut each other in equal halves and at right-angles, so we end up with 4 right-triangles.
now, the sides in a rhombus are all equal, thus the perimeter is 13+13+13+13.
Answer: The formula for the volume of a polygon is 1/2 x perimeter x apothem
Answer:
x=5
/4y+11/2
y=4/5x-22/5
Step-by-step explanation:
$2.19 is the rate of change
Answer:
A =12.92 cm^2
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh where b is the base and h is the height
A = 1/2 ( 7.6) ( 3.4)
A =12.92 cm^2
