In a rectangle whose length is 8 cm and a width of 6 centimeters, a diagonal is drawn. Find the area of the triangle. Find the perimeter of the rectangle.
In a rectangle, the diagonals are equal. Any diagonal divides a rectangle into two equal right-angled triangles. The sides of the rectangle are the legs of the triangle.
The area of a right-angled triangle is half the product of the legs.
Str = 8 * 6: 2 = 48: 2 = 24 (cm2).
The perimeter of a rectangle is the sum of the lengths of its sides.
P = 2 (8 + 6) = 2 * 14 = 28 (cm).
Answer: 24 cm2 and 28 cm.
