Find the area enclosed by each of the following figures :

We know that, area of rectangle = l × b

And area of triangle = × b × h

Area of rectangle = 13 × 4 = 52 cm²

Now, base of triangle = 13 – 8 = 5 cm

And height of triangle = 16 – 4 = 12 cm

Area of triangle = × 5 × 12 = 30 cm²

Total area = Area of rectangle + Area of triangle = 52 + 30 = 82 cm²

∴ Total area = 82 cm²
