(5.3)-+Area+of+A+Triangle

Area of a Triangle: A= 1/2 bc sin A A= 1/2 ac sin B A= 1/2 ab sin C

Heron's Area Formula: A= square root S(S-a)(S-b)(S-c) S= a+b+c/2 Ex. A piece of property has a value of $45 per square foot. The triangular lot has sides of 220 feet, 234 feet, and 160 feet. What is the asking price? S=220+234+160/2=307 A= square root 307(307-220)(307-234)(307-160) A= 16,929.69 $45x16,929.69=$761,836
