Question

The base of an isosceles right triangle is 30 cm, its

area is:

(a) 225 cm² (b)225√3cm² (c ) 225√2cm² (d) 450 cm²​

Answer 1

Answer:

Ok so the triangle is an isosceles right triangle then the height must also be equal to 30cm (as the base is)

Now, area of triangle is 1/2 × base × height.

So area of the given triangle will be

$\frac{1}{2} \times 30 \times 30 = \frac{900}{2 } = 450$

hence option d is correct.
