Find the area to the rhombus
Svetradugi [14.3K]

Answer:

120 cm^2

Step-by-step explanation:

area of a rhombus is pq/2

that means that the product of the two diagonals divided by 2 is the area of the rhombus.

so that means one diagonal is 24 and one is 10, (we are given what half of both diagonals are so just multiply by 2)

now put it in the formula

24x10 = 240

now divide by 2

240/2 = 120

check again with google if u disagree

Sorry it’s small I could not get it in just zoom in
Ne4ueva [31]

Hello!

Graphs A and D are reflected, not rotated, so they are not the answer.

Graph C is rotated 180°, so it is not the answer.

This leaves us with B as our final answer.

I hope this helps!
