Question

Qos Find the area of shaded region in fig.1​

Answer 1

Answer:

28 cm sq.

Step-by-step explanation:

first find the third side(x) which will be:

$x^{2}$ + $15^{2}$ = $17^{2}$

x = $\sqrt{17^{2} - 15^{2} }$

x = $\sqrt{64\\}$

x = 8

x is also equal to the side of the non- shaded triangle and all sides all equal.

so...>

area of the non-shaded triangle will be=

1/2 * 8 * 8

1/2 * 64

= 32 cm sq.

area of large triangle=

1/2 * 15 * 8

1/2 * 120

= 60 cm sq.

area of shaded region will be=

60 cm sq. - 32 cm sq.

= 28 cm sq.
