Answer:
168 mm²
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' =
= 60 mm² - A"=
= 108 mm²
Let's calculate A
- A = A' + A"
- A = 108+ 60
- A = 168 mm²
