Verified Answer
The area of an isosceles right angled triangle of equal side 30 cm, is...
as it is right angle triangle so
area =1/2 x base x height
=1/2 x 30 x 30
= 450 cm2
area =1/2 x base x height
=1/2 x 30 x 30
= 450 cm2

The area of an isosceles right angled triangle of equal side 30 cm, is...
450 cm^2
given,
side of a triangle= 30cm^2
area an isosceles triangle= 1/2( side )^2
=1/2(30)^2.
= 1/2(900)
=900/2
=450 cm^2
given,
side of a triangle= 30cm^2
area an isosceles triangle= 1/2( side )^2
=1/2(30)^2.
= 1/2(900)
=900/2
=450 cm^2

The area of an isosceles right angled triangle of equal side 30 cm, is...
The formula to calculate the area of a triangle is given by:
Area = (base * height) / 2
In an isosceles right-angled triangle, the base and height are equal. Let's call this value x.
So, we have:
Area = (x * x) / 2
Given that the equal sides of the triangle are 30 cm, we can substitute x with 30 cm:
Area = (30 * 30) / 2
Area = 900 / 2
Area = 450 cm²
Therefore, the correct answer is 450 cm².
Area = (base * height) / 2
In an isosceles right-angled triangle, the base and height are equal. Let's call this value x.
So, we have:
Area = (x * x) / 2
Given that the equal sides of the triangle are 30 cm, we can substitute x with 30 cm:
Area = (30 * 30) / 2
Area = 900 / 2
Area = 450 cm²
Therefore, the correct answer is 450 cm².
