Answer:
l=10 cm
Step-by-step explanation:
In a rhombus, the diagonals are cut into identical lines at the intersection.
This way, I found the measures of the halves of the diagonals in a right triangle, knowing that the diagonals of the rhombus are perpendicular on each other.
I calculated that AO = AC/2= 8, and that BO=BD/2= 6, and then I applied pytagora's theorem in a quarter of the rhombus, which is the right triangle AOB, to find the length of a side
It's actually 1, the number used to express a single quantity.
Answer:
D
Step-by-step explanation:
Area = 1/2 a * p
Multiply both sides by 2
2*A = ap
Divide by p
2A / p = a
D
1092 divided by 28 and you will get 42
And 1092 divided by 130 you will get 8.4
-6<x≤8 would be the inequality
