Answer:

I can't answer your 2nd question

HCF is 5

Answer 2

Answer:

HCF of 25 and 40 is 5.

Area of right angled triangle is 1/2 * perpendicular * adjacent base

Step-by-step explanation:

1. Writing down 25 and 40 in multiple of prime factor

 25 = 5 * 5

 40= 2 * 2 * 2 * 5

Therefore Highest common factor is 5.

2. If you cut a rectangle diagonally, you will get two right angle triangle.

   Therefore,

   2 * Area of triangle = Area of rectangle

                                     = Length * breadth

    As length of a triangle is the height & breadth is adjacent base

    Area of triangle= 1/2 (height * base)
