Question

the base of an isosceles right triangle is 30 cm its area is​

Answer 1

Given:-

• Base of an isosceles right triangle = 30 cm

To Find:-

• It's Area

Formula used:-

• Area of right triangle = ${\boxed{\dfrac{1}{2}\times\:Base\times\: Height}}$

Solution:-

As it is given that it's a isosceles right triangle. So, The Base and Perpendicular/Height will be equal as opposite sides of an isoceleles triangle are equal. Then,

• Base = Height = 30 cm

$\implies\:Area=\dfrac{1}{2}\times\:Base\times\: Height$

$\implies\:Area=\dfrac{1}{2}\times\:30\times\: 30$

$\implies\:Area=30 \times 15$

${\boxed{\implies\:Area=450cm^2}}$

Hence, The Area of the given isoceleles right triangle is 450 cm².
