Answer: A = (b²-5b)/2
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Base =b
Height = h = b-5 (the height is 5 units shorter than the base)
Since:
Area of a triangle (A)= (base x height) ÷ 2
Replacing with the values given:
A = [b (b-5)] ÷2
A = (b²-5b)/2
