Question

find area of shaded portion all corners are right angled​

Answer 1

✧ Given :-

• Two rectangles and their sides
• ➝ in big rectangle
• length = 15 m
• breadth = 19.6 m
• ➝ in small rectangle
• length = length of big rectangle – length of shaded part
• = 15 – 2 – 2
• = 11 m
• breadth = breadth of big rectangle – breadth of shaded part
• = 19.6 – 5.4
• = 14.2 m

✧ To Find :-

• Area of shaded part

✧ Explanation :-

• Area of big rectangle = l × b
• = 15 m × 19.6 m
• = 294 m²

• Area of small rectangle = l × b
• = 11 × 14.2
• = 156.2 m²

• Area of shaded part = Area of big rectangle – Area of small rectangle
• = ( 294 – 156.2 ) m²
• = 137.8 m²
