Let's take out the area of rectangle and triangle.

Area of rectangle = Length × Breadth

=> area of rectangle = 25 × 16 = 400 cm²

And area of triangle = 1/2 × base × height

=> 1/2 × 14 × 12

= 7 × 12

= 84 cm²

Now what we can do for finding the remaining portion's area?

Think what would happen if we subtract the triangle's area from the rectangle's?

We will get the area of remaining portion!

So, area of remaining portion = area of rectangle - area of triangle

=> 400 - 84

= 316 cm²
