Question

the altitude of a triangle is three fifth of the length of the corresponding base .if the altitude is increased by 4 cm and the base is decreased by 2 cm,then the area of the remains the same.find the base of the triangle in cm.​

Answer 1

Step-by-step explanation:

the altitude is decreased by, 4 CM and the corresponding base is increased by 10 CM, the area of the triangle remains .

Answer 2

Answer:

Step-by-step explanation:

Let x be the length of altitude of the triangle and y the length of the corresponding base.

Also, according to the question increasing altitude by 4 cm and decreasing base by 2 cm does not change the area of the triangle.

x = 2(12)-4

= 24-4

= 20.
