What is the area of rhombus abcd ? enter your answer in the box. do not round at any steps. units² rhombus a b c d on a coordinate plane with vertex a at negative 1 comma 4, vertex b at 3 comma 2, vertex c at negative 1 comma 0, and vertex d at negative 5 comma 2. point p is at negative 3.4 comma negative 1.2. dashed segments join point p to point d and point p to point c, forming right angle d p c.

  16 units²

Step-by-step explanation:

Diagonal AC is a vertical line extending from y=0 to y=4, so is 4 units long.

Diagonal BD is a horizontal line extending from x=-5 to x=3, so is 8 units long.

The area of a rhombus is half the product of the lengths of the diagonals, so ...

  A = (1/2)(4 units)(8 units) = 16 units²

The area of rhombus ABCD is 16 units².

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
