The length of the rectangle is 8 cm, the perimeter is 24 cm. Draw such a rectangle, divide it into 2 equal triangles. Find the area of each rectangle.

AB = BC = 8 cm – the length of the rectangle,
AD = BC =? cm, the width of the rectangle,
Ravsd = 24 cm,
Равсd = 2 (AB + BC),
2 (AB + BC) = 24,
2 (8 + BC) = 24,
16 + 2BC = 24,
2BC = 24 – 16,
2BC = 8,
BC = 4 (cm).
The width of the rectangle is 4 cm.
We drew a diagonal in the ABCD rectangle, which divided it into two equal triangles:
Sbad = Sbcd = 1/2 * AB * AD = 1/2 * 8 * 4 = 16 kV cm.
Answer: the areas of the triangles are equal and amount to 16 kV cm.
