Question

Find the area of the shaded part

Answer 1

Hey mate!

Here is yr answer....

_______________________________

From the figure,

Area of the shaded region = area of trapezium - area of square

Now,

h = 5cm, a = 10cm, b = 16cm

Area of trapezium = 1/2 h(a+b)

= 1/2 × 5(10+16)

= 1/2 × 5(26)

= 1/2 × 130

= 65 sq.cm

And,

side (a) = 3cm

Area of square = a²

= 3²

= 9 sq.cm

Then,

Area of shaded region = 65 - 9 = 56

Therefore, area of shaded region = 56 sq.cm
