Equation for area = 36 = [1/2]x[2x - 1]
Step-by-step explanation:
Given:
Area of triangle = 36 m²
Length of base = 2(Height) - 1
Find:
Equation for area
Computation:
Assume;
Height = x
Area of triangle = (1/2)(b)(h)
36 = (1/2)[2(x) - 1][x]
36 = [1/2]x[2x - 1]
Equation for area = 36 = [1/2]x[2x - 1]
