Question

Find the area of an isosceles right triangle if one of its right side is 18 cm long

Answer 1

area = (1/2)bh

= (1/2) × 18 × 18

= 324/2

= 162 cm square..

Answer 2

Answer:

Area of the triangle is 162 square cm.

Step-by-step explanation:

In the question,

We have been provided a right angled isosceles triangle with the length of the side = 18 cm

Now,

We know that,

Area of the isosceles right angle triangle is,

$A=\frac{1}{2}\times base \times height$

Because, it is an isosceles triangle we know that the length of the base and the height are going to be same.

So,

$A=\frac{1}{2}\times 18\times 18=18 \times 9 = 162cm^{2}$

Therefore, the Area of the triangle is 162 square cm.
