Question

Какие длины сторон могут быть у прямоугольника площадью 80 мм2?

Answer 1

S=ab=600 мм²
b=S/a
1 прямоугольник:
а=10 мм
b= 600/10=60 мм
Р=2(a+b)=2(10+60)=2*70=140 мм - периметр

2 прямоугольник
а=15 мм
b= 600/15=40 мм
Р=2(a+b)=2(15+40)=2*55=110 мм - периметр

3 прямоугольник
а=20 мм
b= 600/20=30 мм
Р=2(a+b)=2(20+30)=2*50=100 мм - периметр

Answer 2

Finding the Side Lengths of a Rectangle with an Area of 80 mm²

To find the possible side lengths of a rectangle with an area of 80 mm², we can use the formula for the area of a rectangle, which is given by the product of its length and width: Area = length × width.

Given that the area is 80 mm², we can find the possible combinations of length and width that satisfy this condition.

Let's calculate the possible side lengths based on the given area.

The formula for the area of a rectangle is: Area = length × width

We can solve for the side lengths using the given area of 80 mm².

Calculation:

We can find the possible side lengths by considering all the factors of 80 and pairing them up to form length and width combinations.

The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

Pairing these factors, we get the following combinations: (1, 80), (2, 40), (4, 20), (5, 16), (8, 10)

So, the possible side lengths of a rectangle with an area of 80 mm² are: 1. Length = 1 mm, Width = 80 mm 2. Length = 2 mm, Width = 40 mm 3. Length = 4 mm, Width = 20 mm 4. Length = 5 mm, Width = 16 mm 5. Length = 8 mm, Width = 10 mm

These are the possible combinations of side lengths for a rectangle with an area of 80 mm².
