Question

the perimeter of an isosceles right angled triangle is 6(1.41 + 1) cm find its area​

Answer 1

Answer:

∠A=∠C ( since it is a right angled isosceles triangle )

⇒AB=BC ( sides opposite to equal angles are equal )

Let AB=BC=x

Area =5000m

⇒x=100m

⇒AC=

100

m

=100×1.41m

=141m

⇒ Perimeter =AB+BC+AC

=100+100+141

=341m.

Hence, the answer is 34
