Answer: (a) 12.44 - 3.11h = 0
(b) 4in²
Explanation:
Area of a triangle = (1/2)bh, where b is the base and h is the height.
Now from the question, Area = 6.22in² and the base is 3.11inches.
Therefore, the equation that relates the area to the height and the base wiil be
Area = (3.11)h/2
6.22 x 2 = 3.11 x h
12.44 = 3.11h
12.44 - 3.11h = 0
(b) to find the value of h from the equation, make h the subject of the formula by solving for h
12.44 = 3.11h
h = 12.44/3.11
= 4in²
