Sagot :
Answer:
A = 5 units²
Step-by-step explanation:
The area (A) of a rhombus is calculated as
A = [tex]\frac{1}{2}[/tex] × d₁ × d₂
d₁ = x + 4 = 1 + 4 = 5
d₂ = 2y - 4 = 2(3) - 4 = 6 - 4 = 2 , then
A = [tex]\frac{1}{2}[/tex] × 5 × 2 = 5 units²
Answer:
A= 5m
Step-by-step explanation:
The equation to find the area of a rhombus, when knowing the diagonals, is:
- 1/2×d1×d2
To solve this, we have to find first d1 and d2, which are marked in a parenthesis:
- d1= (x+4)m, where x=1
- d1= 5m
d1= 5m. Now, let's find d2:
- d2= (2y-4)m, and y=3
- d2= (6-4)m
- d2= 2m
Knowing the values of both diameters, we can solve the equation for the area:
- A= 1/2×d1×d2
- A= 1/2×5m×2m
- A= 1/2×10m
- A= 5m
The area of the rhombus is 5 meters.
