Question

22. Find the area of right angled triangle
ABC in which AB=AC=4 cm and right angle
is at A.*​

Answer 1

Answer:

8 cm sq.

Step-by-step explanation:

Given that,

There is a ∆ABC such that, it is right angled at vertex A.

Also, the length of sides are given as,

• AB = 4 cm
• AC = 4cm

To find the area of ∆ABC.

$\red{Diagram:-}$ Refer to the attachment.

In the drawn figure of ∆ABC, we cam Clearly see that,

AB is the perpendicular length of ∆ABC and,

AC is the base length of ∆ABC.

Now, we know that,

Area of right ∆ = ½ × perpendicular × base

Therefore, we will get,

=> ar(∆ABC) = ½ × 4 × 4

=> ar(∆ABC) = 2 × 4

=> ar(∆ABC) = 8

Hence, the required area of ∆ABC is 8 cm sq.
