Question

The base of an isosceles right triangle is 30 cm its area is. *
a) 225 sq.cm
b) 2253 sq.cm
c) 225 2 sq.cm
d) 450 sq.cm​

Answer 1

Answer:

450 sq.cm

Step-by-step explanation:

Given that ABC is an isosceles right triangle

since, the base BC = 30 cm ,

therefore, AB = 30 cm.

Area of ABC = 1/2 * AB * BC

= 1/2 *30 * 30 cm

= 450 sq.cm

Answer 2

PROVIDED:-

• △ABC is an isosceles triangle.
• Base = BC = 30 cm

TO FIND:-

• Area of △ABC

SOLUTION:-

As we know,

Base BC = 30 cm,

•°• AB = 30 cm

According to the question,

★Area of △ABC :

⇒ A = 1/2 × AB × BC

⇒ A = 1/2 × 30 × 30

⇒ 450 cm^2

Hence,

• Area △ABC is 450 cm^2
• Therefore, option d) is correct.
