Question

please answer correctly​

Answer 1

Answer:

32m^2

Step-by-step explanation:

Total area of rectangle is 4×10 = 40m^2

Area of shaded region = area of total fig. - area of unshaded region

= ((1/2)×3×2) + ((1/2)×5×2)

= 3 + 5

= 8

That gives rise to 40 - 8 = 32m^2

Answer 2

Answer:

Area of the shaded region = 32 m².

Step-by-step explanation:

Area of whole rectangle = l × b

= 10 × 4

= 40 m²

unshaded figures are two triangles .

Area of triangle A = ½ × b × h

= ½ × 3 × 2

= 3 m²

Area of triangle B = ½ × b × h

= ½ × 5 × 2

= 5 m²

Here , height is taken two because the second side is parallel of rectangle and it in divided equally in two parts and then formed triangles .

Area of shaded region = 40 m² - ( ∆ A + ∆ B )

= 40 m² - ( 3 + 5 ) m

= 40 - 8

= 32 m²

therefore the area of shaded region is 32 m².
