Question

find the area of the shaded region in the figure given alongside.​

Answer 1

Answer:

the answer of this question is : 50

Answer 2

Area of the shaded region = 150m²

Step-by-step explanation

Area of the rectangle = l × b

= 10 × 20

= 300m²

Area of the unshaded region = Sum of the areas of the unshaded triangles

Area of the unshaded triangle 1 = ½ × 12 × 10

= 60m²

Area of the unshaded triangle 2 = ½ × 20 × 5

= 50m²

Area of the unshaded triangle 3 = ½ × 8 × 10

= 40m²

Therefore, area of the unshaded region

= 60 + 50 + 40

= 150m²

Area of the shaded region = Area of the rectangle - Area of the unshaded region

= 300m² - 150m²

= 150m²
