the height of a triangle is 2 centimetres more than the base. if the height is increased by 2 centimetres while the base remains

tia_tia [17]

Answer:

Base = 11 cm

Height = 13 cm

Step-by-step explanation:

It is given that the height of a triangle is 2 centimetres more than the base.

Let x cm be the base of triangle. So height of the triangle is x+2 cm.

It is given that if the height is increased by 2 centimetres while the base remains the same, the new area becomes 82.5 centimetres square.

New height = (x+2)+2 = x+4 cm

Area of a triangle is

$A=\dfrac{1}{2}\times base\times height$

$82.5=\dfrac{1}{2}\times x\times (x+4)$

$165=x^2+4x$

$x^2+4x-165=0$

Splitting the middle term, we get

$x^2+15x-11x-165=0$

$x(x+15)-11(x+15)=0$

$(x+15)(x-11)=0$

Using zero product property, we get

$x=-15,11$

Base of a triangle can not be negative, therefore x=11.

Base = 11 cm

Height = 11+2 = 13 cm

Therefore, the base of original triangle is 11 cm and height is 13 cm.
