Find the area enclosed by the following figure:

बेरीज

उत्तर


The given shape has a triangle and a rectangle

For rectangle, l = 13 cm and b = 4 cm

∴ Area of rectangle = l × b = 13 × 4 = 52 cm2

For triangle, base (b) = 5 cm

and height (h) = (16 – 4) cm = 12 cm

∴ Area of triangle = `1/2` × b × h = `1/2` × 5 × 12 = 30 cm2

∴ Total area enclosed by the shape = (52 + 30) cm2 = 82 cm2.
