Question

The area of a right angle triangle is 10 square centimetre if its perpendicular is equal to 20 cm find its base

Answer 1

area of right angle triangle = (1/2)×base × height

area = 10 cm^2

perpendicular and height are the same thing

so height of right angle triangle = 20cm

10 = (1/2)×Base × 20

=> 20 = Base × 20

dividing both side by 20

=> 1 = Base

=> Base = 1 cm

Base of right angle triangle = 1 cm
