Answer:
168 mm²
Step-by-step explanation:
Let A be the area of this shape
the kite is made of two triangles
Let A' and A" be the areas of the triangles
let's calculate A' and A" :
The area of a triangle is the product of the base and the height over 2
- A' = [tex]\frac{(12+12)*5}{2}[/tex] = 60 mm²
- A"= [tex]\frac{(12+12)*9}{2}[/tex] = 108 mm²
Let's calculate A
- A = A' + A"
- A = 108+ 60
- A = 168 mm²
