Question

Длинные сторон прямоугольника 80 см и 5 см Вычисли периметр и площадь этого прямоугольника

Answer 1

P=(a+b)
(80+5)*2=170(см)- периметр прямоугольника
 

S=a*b
80*5=400(см 2)-площадь прямоугольника

Ответ: периметр прямоугольника равен 170 см, а площадь равна 400 см2

Answer 2

1) (80+5)*2=170(см)-Р.
2) 80*5=400(см²)- S.
Ответ: 170 см, 400 см².

Answer 3

Calculation of Perimeter and Area of a Rectangle

To calculate the perimeter and area of a rectangle, we need to know the lengths of its sides. In this case, the lengths of the sides are given as 80 cm and 5 cm.

Perimeter is the sum of all the sides of a rectangle. For a rectangle with sides of length a and b, the perimeter (P) is given by the formula:

P = 2(a + b) Substituting the given values, we have:

P = 2(80 cm + 5 cm) P = 2(85 cm) P = 170 cm

Therefore, the perimeter of the rectangle is 170 cm.

Area is the measure of the region enclosed by the rectangle. For a rectangle with sides of length a and b, the area (A) is given by the formula:

A = a * b Substituting the given values, we have:

A = 80 cm * 5 cm A = 400 cm²

Therefore, the area of the rectangle is 400 cm².

To summarize: - Perimeter of the rectangle: 170 cm - Area of the rectangle: 400 cm²
