Answer 1

Answer:

(a)...6cm

Step-by-step explanation:

Given:-

Side of each triangle will be 8 cm and 10 cm.

By using Pythagoras theorem

a²=b²+c²

10²=8²+c²

c=√(10²-8²)

c=√36

c=6 cm.

So, breadth of a rectangle is 6cm.

Answer 2

-------------------------------------------------------------

We know, length and breadth of rectangle are perpendicular to each other, then

By Pythagoras theorem,

length² + breadth² = diagonal²

8² + breadth² = 20²

Breadth²2 = 200 - 64

breadth = √164= 12.80cm

---------------------------------------------------------

You have written 20 cm or 10 cm?
