Question

Find The area if an isosceles right Triangle, if one of its right sides is 18 cn long​

Answer 1

Answer:

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,

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.
