Triangles with the same base and between the same parallels are of
Equal area
Equal perimeter
Both 1 & 2
None of these
The area of an equilateral triangle is numerically equal to its perimeter . Find the length of its side.
√3 units
2√3 units
3√3 unit
4√3 unit
A square and an equilateral triangle have equal perimeters. If the diagonal of the square is , then the area of the triangle is
Area of an equilateral triangle with side x is
1/2 x2
x2
4/3 x2
In Heron's formula, s represents
Perimeter of the triangle
Semi-perimeter of the triangle
Hypotenuse
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
10cm, 8cm
15cm, 8cm
15cm, 10cm
12cm, 8cm
In a right triangle with sides x and y, hypotenuse z, the altitude drawn on the hypotenuse is a, then
xy = a2
1/x + 1/y = 1/a
x2 + y2 = 2a2
Heron's formula is used to find the area of
Rectangle
Parallelogram
Trapezium
Triangle
A triangle has a height of 6cm and its area is 30cm2, what is the length of its base
10cm
12cm
13cm
15cm
If the sides of a triangle are doubled, then its area
Remains the same
Becomes doubled
Becomes three times
Becomes four times
