Question

find the area of shaded protion.​

Answer 1

Answer:

484

Step-by-step explanation:

as ABD is a right angled triangle so we can calculate its hypotanuse AB which is 20 cm. $\sqrt{x} 16x^{2} +12x^{2}$

again the area of triangle ABC is = 1/2×base×height

so area of ABC= 480cm$x^{2}$

similarly area of ABD is 96 cm$x^{2}$

so area of shaded portion is = area of ABC - area of ABD

= 480 - 96 = 484

Answer 2

Answer:

Answer:

484

Step-by-step explanation:

as ABD is a right angled triangle so we can calculate its hypotanuse AB which is 20 cm.

again the area of triangle ABC is = 1/2×base×height

so area of ABC= 480cm

\begin{gathered}x^{2} \\\end{gathered}

Step-by-step explanation:

similarly area of ABD is 96 cm

x^{2}

so area of shaded portion is = area of ABC - area of ABD

= 480 - 96 = 484
