Answer 2

Answer:

91 unit²

Step-by-step explanation:

I have split the given figure into two (blue) identical rectangles with length =8 and breadth =3.5

And four (pink) identical triangles with height=5 and base=3.5

So,

all set...

Let's sum up :)

Area of the figure = 2×(Area of a rectangle) + 4×(Area of a triangle)

we know that,

Area of a rectangle = length (l) × breadth (b)

Area of a triangle = 1/2 × base (b) × height (h)

thus,

substitute the values,

Area of figure =2( 8×3.5 ) + 4 (1/2 × 3.5 × 5)

= 56 + 35

= 91 unit²
