Question 285495
let the base be x

The height will be x+1

Area of triangle = 1/2 * base * height

=1/2 *x *(x+1)

1/2 x^2 +1/2*x = 15

x^2+x=30

x^+x-30=0

x^2 +6x-5x-30

x(x+6)-5(x+6)=0

(x+6)(x-5)=0

x=-6 or 5

It cabt be negative so x= 5 which is the base of the tooth

height will be 5+1=6 cms.
