No.
Two sides of a triangle are not sufficient to determine its area.
Scalene
No. The two shortest sides, 2cm and 4cm, add up to 6cm. 6 cm is shorter than 7cm, so those three sides will not make a triangle.
The height has not been given but the area of the triangle is: 0.5*height*base
No.
The area of triangle is : 42.0
Two sides of a triangle are not sufficient to determine its area.
Area 51.
Scalene
No. The two shortest sides, 2cm and 4cm, add up to 6cm. 6 cm is shorter than 7cm, so those three sides will not make a triangle.
Yes, it can. And if you do the math, some basic trigonometry, you can calculate the angles in the triangle.
if it is a scalene triangle yes scalene triangle have no congruent sides and angles
It is: 3*7 = 21cm
A scalene triangle is simply a triangle where all of its sides are different lengths. One example of the side lengths of a scalene triangle are: 5cm, 6cm and 7cm
17.5cm squared
To find the area of a triangle, you can use the formula: Area = 0.5 * base * height. In this case, the base is 5cm and the height is 7cm. Plugging these values into the formula, we get Area = 0.5 * 5cm * 7cm = 17.5 square centimeters. Therefore, the area of the triangle is 17.5 square centimeters.
