Question

For each find the area of shaded region

Answer 1

Answer:

Answer is 27cm²

Step-by-step explanation:

So, the area of the coloured portion = Area of tripazium - Area of triangle

Now, Area of tripazium = 1/2 × h (sum of parallel sides)

area= 1/2 × 12(9 + 17)

area = 6 × 26

area = 156cm²

So, Area of triangle = 1/2 × b × h

area = 1/2 × 17 × 6

area = 17 × 3

area = 51cm²

Therefore, Area of coloured portion = 156 - 51

Area = 105cm²

Answer is 105cm²
