Question

The area of a right angled triangle whose base is 12.5 cm and height is 20 cm.

Answer 1

⭐Answer:

Area of triangle= 125 cm^2 .

⭐Step-by-step explanation:

➡Area of Right angled triangle = 1/2 Base x height

✔Area of triangle = 1/2 × 12.5 × 20

✔Area of triangle= 12.5 × 10

✔Area of triangle= 125 cm^2

Answer 2

Right angled triangle :

  • A right angled triangle is the triangle with an angle 90°, i.e., a right angle.

  • By Pythagorean theorem, a right angled triangle will have a base (a), a height (b) and a hypotenuse (c) with a relation

         $\boxed{\bold{a^{2} + b^{2} = c^{2}}}$

Area Formula for right angled triangle :

  If a right angled triangle is having base of b units and height of h units, its area be

         = $\frac{1}{2}$bh unit²

Given data is

  The base of the right angled triangle is 12.5 cm and height is 20 cm

Therefore, the area of the right angled triangle be

  = $\frac{1}{2}$ * base * height unit²

  = $\frac{1}{2}$ * 12.5 * 20 cm²

  = 12.5 * 10 cm²

  = 125 cm²
