Question

Find the area and perimeter of the triangle. See picture for problem. Please and thank you so very much!(:

Answer 1

Area = 2.28 sq km

Perimeter = 13.7 km

Explanation:

`A(\triangle)=(1)/(2)(1.2)(3.8)`

`\implies A(\triangle)=(1.2)(1.9)`

`\implies \boxed{\red{\bold{A(\triangle)=2.28\:km^2}}}`

`P(\triangle)=7+1.2+5.5`

`\implies \boxed{\purple{\bold{P(\triangle)=13.7\: km}}}`
