Answer 1

Answer:

40cm, 30cm

Step-by-step explanation:

Let the altitude BC of right-angled triangle ABC be x cm. Then,

Base = BC = (x+10) cm

Area = 1/2(x+10)x cm ^2

1/2x(x+10)=600

x^2+10x=1200

x^2+10x−1200=0

x^2+40x−30x−1200=0

x(x+40)−30(x+40)=0

(x+40)(x−30)=0

x=30,−40

Hence, Base = 40 cm and Altitude = 30 cm.
