Answer 1

Answer:

Lenght =12cm breath=8cm highest=5cm volume how the answer

Answer 2

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

2

+100

2

=100

m

=100×1.41m

=141m

⇒ Perimeter =AB+BC+AC

=100+100+141

=341m.

Hence, the answer is 341.
