Question

WILL MARK BRAINLIEST PLEASE HELP

Answer 1

Answer:

A = 5 units²

Step-by-step explanation:

The area (A) of a rhombus is calculated as

A = $\frac{1}{2}$ × d₁ × d₂

d₁ = x + 4 = 1 + 4 = 5

d₂ = 2y - 4 = 2(3) - 4 = 6 - 4 = 2 , then

A = $\frac{1}{2}$ × 5 × 2 = 5 units²

Answer 2

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.

Hope it helps!!
