Determine the area of the triangle if the circumference is 22 cm. In an isosceles triangle, the length of the base is equal to 75% of the arm's length. Calculate the length of sides and determine whether a triangle is a right triangle.ĭetermine area S of a rectangle and the length of its sides if its perimeter is 102 cm. Side b is 1 cm longer than c, and side c is 31 cm longer than side a.
