Q2. - Geometry

Question

Find the areas of$△ABC,△DBC$ and$△EBC$ .

Step-by-Step Solution

Answer

The Area of triangles$\Delta ABC,\Delta DBC,\Delta EBC$ are 18 square unit.

Step 1. Given information.

Base is$b=9$ and height is$h=4$ .

Step 2. Concept used.

Area of triangles$\Delta ABC,\Delta DBC,\Delta EBC$ are equal because the base and height are same for all three triangles.

And, the Area of triangle is given as

$\frac{1}{2}\times b\times h$

Step 3. Find the area of triangles.

Calculation:

Area of $\Delta ABC=\frac{1}{2}\times 9\times 4$

                 $=18$    Square units

Area of $\Delta DBC=\frac{1}{2}\times 9\times 4$

                    $=18$  Square units

Area of $\Delta EBC=\frac{1}{2}\times 9\times 4$

                  $=18$    Square units

 

 

Therefore, the Area of triangles$\Delta ABC,\Delta DBC,\Delta EBC$ are18 square units.
