Question

The base of a triangle is x cm and its height is (x-7) Write down the expression of the triangle

Answer 1

Explanation:

if you mean the area of the triangle then it is S = 1/2*x(x-7)

Answer 2

Explanation:

b= x cm

h = (x - 7) cm

Area of triangle =
`(1)/(2)*x*(x-7)\\\\`

`(x*x-x*7)/(2)\\\\=(x^(2)-7x)/(2)` square cm
