Question

Find area of isosceles triangle 13cm 10cm

Answer 1

65 cm^2 or centimeter squared

Explanation:

area of a triangle is

1/2 * b * h

1/2 * 13 * 10

65

Answer 2

The area of isosceles triangle is 65 cm².

Step-by-step explanation:

SOLUTION :

Here's the required formula to find the area of Isosceles triangle :

`\longrightarrow{\pmb{\sf{A = (1)/(2) bh}}}`

• A = Area
• b = base
• h = height

Substituting all the given values in the formula to find the area of Isosceles triangle :

`\implies{\sf{A_((\triangle)) = (1)/(2) bh}}`

`\implies{\sf{A_((\triangle)) = (1)/(2) * b * h}}`

`\implies{\sf{A_((\triangle)) = (1)/(2) * 13 * 10}}`

`\implies{\sf{A_((\triangle)) = \frac{1}{\cancel{2}} * 13 * \cancel{10}}}`

`\implies{\sf{A_((\triangle)) = 1 * 13 * 5}}`

`\implies{\sf{A_((\triangle)) = 13 * 5}}`

`\implies{\sf{A_((\triangle)) = 65}}`

`\star{\boxed{\sf{\red{A_((\triangle)) = 65 \: {cm}^(2)}}}}`

Hence, the area of isosceles triangle is 65 cm².
