The base of the right-angled triangle = 4 units The height = 6 units The area = 0.5 * base * height = 12 square units =========================
h.8 square units
If you mean vertices of: (-1, -1) (-1, 3) and (5, -1) then when plotted on the Cartesian plane it will form a right angle triangle with a base of 6 units and a height of 4 units. Area of triangle: 0.5*6*4 = 12 square units
1&12, 2&6, 3&4!
The area of a triangle is half base times height so any triangles whose base times height is 60 units will have an area of 30 square units e.g. base = 10 units, height = 6 units; base = 5 units, height = 12 units; base = 7.5 units, height = 8 units.
The area of triangle is : 12.0
The area of triangle is : 78.0
A triangle with side a: 7, side b: 12, and side c: 11 units has an area of 37.95 square units.
A = leg1leg2/2 = (8)(12)/2 = 48
Area = 0.5*5*12 = 30 square units
It is: 0.5*12*15 = 90 square units
It is: 0.5*10*12 = 60 square units
Area = 0.5*12*8 = 48 square units
Perimeter = 10 + 10 + 12 = 32 units. Area = 48 square units
1/2*10*12 = 60 square units
Square with side of 12 units => area = 12*12 sq units = 144 square units.
Area = 0.5 * base * height = 0.5 * 12 * 10 = 60 square units.
