Question

What is the area of a triangle that has a base of 3 feet and a height of 6 feet? 18 ft 2 18 ft 9 ft 2 4.5 ft 2

Answer 1

Solution:-

Given:-

Base = 3 feet.

Height = 6 feet.

To Find:-

Area of Triangle = ?

Find:-

We know that,

Area of Triangle = 1/2 × Base × Height

=) Area = 1/2 × ( 3 × 6 )

=) Area = 3 × 3

=) Area = 9 feet²

Hence,

Area of Triangle is 9 feet².

Formulas!

• Area of Triangle = 1/2( Base × Height)

For Scaler Triangle:-

• Semi-perimeter (s) = ( a + b + c)/2
• Area = √ [ s(s-a)(s-b)(s-c) ]

For Equilateral Triangle:-

• Area = a²√3/4
• Height = a√3/2
