Question

How do I find the area of this shape. Please help I need to turn this in today

Answer 1

A = 70 units²

Explanation:

Since all 4 sides are congruent then figure is a rhombus

The area (A) of a rhombus is calculated as

A =
`(1)/(2)` × d₁ × d₂ ( d₁ and d₂ are the diagonals )

Here d₁ = 7 + 7 = 14 and d₂ = 5 + 5 = 10 , then

A =
`(1)/(2)` × 14 × 10 = 7 × 10 = 70 units²
