Question

Find the heigt of a right triangle anhle triangle whose base is 15cm and area is 90cm²

Answer 1

Answer:

The area of triangle=90cm^2

The base=15cm

The altitude=x

The area of triange= 1/2×base×height

90cm=1/2×15cm×x

90cm×2=15cm×x

180cm=15cm×x

X=180/15

X=12

Answer 2

Given :

• The base of the right triangle = 15 cm.
• The area of the right triangle = 90 cm².

To find :

• The height of the right triangle =?

Formula Used :

• Area of the triangle = 1/2 × base × height

Step-by-step explanation :

It is Given that,

The base of the right triangle = 15 cm.

The area of the right triangle = 90 cm².

As We know that,

Area of the triangle = 1/2 × base × height

Substituting the values in the above formula, we get,

90 = 1/2 × 15 × h [height = h]

15 × h = 90 × 2

h = 90 × 2/15

h = 6 × 2

h = 12.

Therefore, The height of the right triangle = 12 cm.
