Question

A triangle has an area of 50 meters squared. The base is 7 less than 2 times the height. What is the height and the base of the triangle.

Answer 1

(1/2) (Base) (Height) = AREA

(1/2)(2h-7)h = 50

(2h-7)h = 100 <--- multiplies by 2

2h^2 - 7h = 100 <--- distributive

2h^2 - 7h - 100 = 0

h = (7 +or- sqrt( 49 - 4*2*-100))/4

= (7 +or- sqrt( 49 + 800))/4

= (7 + sqrt(849)) / 4

B = 2h - 7

= (7+sqrt(849))/2 - 7

= (7 + sqrt(849) - 14)/2

= (sqrt(849) - 7)/2

(1/2) (sqrt(849)-7)/2 ( 7+ sqrt(849))/4

= (Sqrt(849) - 7) ( sqrt(849)+7) / 16

= (849 - 49)/ 16 = 800/16 = 50

Answer 2

hl/2=50

l=2h-7

h(2h-7)/2=50

2h^2-7h=100

h=9.0345

l=100/h=11.069
