Triangles with the same base and between the same parallels are of 

Δ ABC shown below is inscribed inside a square of side 20cm. Find the area of the triangle

Area of a triangle if its base, b and height, h are given is 

Heron's formula is 

A triangle has a height of 6cm and its area is 30cm², what is the length of its base

In Heron's formula, s represents

The base of the traingle is 15dm and its height is 12dm. The height of another triangle of double the area and the base of which is 20 dm is

The sides of a triangle containing the right angle are 5x cm and (3x - 1) cm. If the area of the triangle is 60cm², calculate the length of the sides

The area of right angled triangle is 20cm² and one of the sides containing the right triangle is 4 cm. Then the altitude on the hypotenuse is 

The area of triangle whose sides are 3cm, 4cm and 5cm is
