this is 5cm (:
Its height is: 8 feet
Area of a triangle = 1/2 x base x altitude(height)On putting given values, we get45cm2 = 1/2 x 6cm x height(altitude)cm45 = 3 x altitudealtitude = 15 cmAnswer to the question is 15cm.
132 ft
Area = 1/2 base * perpendicular height so 1/2*21*9 =94.5 square units
That means that the height should be measured perpendicular to some other line (or plane in some cases). For example, to calculate the area of a triangle, the formula is (1/2) x base x height, where the height must be measured perpendicular to the base.
The area is 108cm2
Area is 36cm2
The area of triangle is : 18.0
Area of a triangle = 1/2 (Base x Height) Example: Width 13cm, Height 5cm, Base 12cm then; Area=1/2(12cm x 5cm) Area=6cm x 5cm Area=30cm2
The area of a triangle = (base * height) / 2. So here, the area = 12 * 7 / 2 = 84/2 = 42 cm2.
3.5
Area of a triangle = 1/2 * Base * Height = 1/2 * 12 * 6.5 = 39 cm2
=48
60 sq cm
Base x Height / 2 So it's 12x8.5/2= 51
Given that,base = 10 cm and height = 12 cm.The area of a triangle = 1/2 * base * height= 1/2 * 10 * 12= 5 * 12= 60 sq.cm.
The area of any triangle is found by multiplying 0.5 x base x perpendicular height (the height of the triangle that is located at a right angle to the base). So for your dimensions, Area = 0.5 x 12 x 6.5 = 39 cm2
