Question

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

Answer 1

Step-by-step explanation:

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

Answer 2

Answer:

Step-by-step explanation:

b= x cm

h = (x - 7) cm

Area of triangle = $\frac{1}{2}*x*(x-7)$

                           $\frac{x*x-x*7}{2}\\\\=\frac{x^{2}-7x}{2}$   square cm
