Find the area of the shaded region ​

Answer»

GivEn:-

  • The length of rectangle is 12 CM and BREDTH of rectangle is 8 cm.
  • The base of triangle is 8 cm and HEIGHT of triangle is 4 cm

To FiNd:-

  • The area of shaded region.

AnaLySis:-

  • To find the area of shaded region we've to firstly find the area of rectangle and triangle.

Formulas UsEd:-

  • Area of triangle
  • Area of rectangle

SoLuTioN:-

Area of rectangle:-

\large \boxed{ \red{length \times bredth}} \\ \\ = 12 \times 8 \\ \\ = \boxed{{96 \: cm}^{2} }

Area of triangle:-

\large \boxed{ \red{base \times height \times \frac{1}{2}}} \\ \\ = 8 \times 4 \times \frac{1}{2} \\ \\ = 32 \times \frac{1}{2} \\ \\ = 16

Area of shaded region:-

\large \boxed {\red{area \: of \: rectangle - area \: of \: triangle}} \\ \\ = 96 - 16 \\ \\ = {80}^{2}

Hence,the area of shaded region is {80}^{2}
