Question

please solve any 2 of them​

Answer 1

Answer:

25) Area= 96cm²

26) 4/5

Step-by-step explanation:

25) In the given right angled triangle

H²= P²+B²

(20)²= P²+(16)²

400= P²+ 256

400-256= P²

144= P²

12cm= P= Height

Area of triangle= 1/2×base×height

= 1/2×16×12 = 16×6

= 96cm²

26) Total no. of balls= 30

No. of times ball hits the boundary= 6

No. of times ball didn't hit the boundary= 30-6= 24

$probability = \frac{no. \: of \: favourable \:outcomes }{total \: outcomes}$

P(ball didn't hit the boundary)= 24/ 30

= 4/5

Hope It Helps :)
