Question

the base of triangle is 18 more than 2 times of its height if the area of the triangle is 360 square metre then let us determine the height of it​

Answer 1

Answer:

height cannot be negative

therefore x=15m

Answer 2

Answer:

height =15m

Step-by-step explanation:

Let the height be x m

base =(18+2x )m

area =360sq m

According to the problem,

1\2 x base x height =360

or, 1\2 * x *(18 +2x)

or, (18x +2x) \2 =360

or, 18x + 2x²=720

or, 18 +2x²-720 =0

or, 9x +x² -360 =0

or, x² +24 x -15x -360=0

or, x(x+24)-15(x+24 )=0

or, (x+24 ) (x -15)=0

either ,

X=-24 or x =15

height =15m ...

ans :the required height is 15m
