Answer 1

Step-by-step explanation:

all explanation is there

Answer 2

Answer:

Step-by-step explanation:

let the one side be 'x'

x = 7 cm

let the another side be 'y'

pythagoras theorem,

=> x² + y² = h²

=> 7²+y² = 25²

=> 49 + y² = 625

=> y² = 625 - 49

=> y² = 576

=> y = 24

area of the right angled triangle,

=> 1/2*b*h

=> 1/2*7*24 = 7*12

=> 84 sq cm
