A triangle has a base of 4 units and a corresponding height of 12 units. What is its area?​

24 units^2

Step-by-step explanation:

A=1/2*b*h

A=1/2*4*12=1/2*48=48/2=24

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
