Question

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

Short answer

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

Step-by-step solution

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.
