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.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

for future students the answer is b

hope i
