Step-by-step explanation:
Area = 1/2 * base * height
48 = 1/2 * 16 * h
h = 48/8 = 6 cm
The height divides the isosceles triangle into two equal right triangles the hypotenuse of these 2 triangles which is also the equal side of the isosceles triangle is calculated as:
s = √(8^2 + 6^2) = √100 = 10 cm
thus the perimeter is:
P = 2 * 10 + 16 = 36 cm
