Question

A triangular traffic island has a base half as long as it's height. The island has an area of 576m. Find the base and the height

Answer 1

let the height be x then 

base of island =  x/2 

area of island = 1/2* x/2* x = x2 / 4 = 576m

Answer 2

a triangular traffic Island has a base half as long as its height. Find the base and the heightif the Island has an area of 64m^2
------------------
b = h/2
----------------
A = (1/2)b*h
----------------

64 = (1/2)(h/2)h
64 = (h/2)^2
h/2 = 8
h = 16 meters
