Question

The base of a triangle is half its height and area of the triangle is 36 cm square. The length of the base of the triangle is
(i) 6cm (ii) 4 cm (iii) 12 cm (iv) 18 cm ​

Answer 1

Answer:

(i) 6cm

Step-by-step explanation:

base(b)=height(h)/2

area of triangle=1/2 × base × height

36=1/2 × h/2 × h

36=h^2/4

h^2=36 × 4

h^2=144

h=√144

h=12cm

h/2=12/2=6cm
