Use 105 squares of the same size to make a rectangle, with______ There are two different spellings

Use 105 squares of the same size to make a rectangle, with______ There are two different spellings

The divisors of 105 are: 1, 3, 5, 7, 15, 21, 35, 105; 105 = 1 × 105; 105 = 3 × 35; 105 = 5 × 21; 105 = 7 × 15; so the length and width of the rectangle that can be assembled are 105 and 1, 35 and 3, 21 and 5, 15 and 7 respectively; a: four different kinds of rectangles can be assembled

Xiao Ming wants to use 105 square cards of the same size to make a rectangle. How many kinds of spelling are there

This exercise can be solved as follows: 105 = 1 × 105 = 3 × 35 = 5 × 21 = 7 × 15. There are four combinations, so there are four spelling methods
The factors of 105 can be divided into four groups: 1, 3, 5, 7, 15, 21, 35, 105

How many different spellings are there for 48 squares of the same size to make a rectangle

This question is actually asking how many "products of two numbers" 48 can be decomposed into. Starting from 1, there are five spelling methods: 1 * 48, 2 * 24, 3 * 16, 4 * 12, 6 * 8

Use 48 squares of the same size to make a rectangle, with______ There are two different spellings

According to the stem analysis, we can get: 48 = 1 × 48 = 2 × 24 = 3 × 16 = 4 × 12 = 6 × 8, then there are five ways to form a rectangle with 48 small squares

How many different spellings are there to make a rectangle with 24 squares of the same size?

1×24
2×12
3×8
4×6
There are four kinds

How many different spellings are there to make a rectangle with 54 squares of the same size?
I hope I can finish it in five minutes

54=1×54
54=2×27
54=3×18
54=6×9
So there are four

Put 12 small squares with an area of 1 square centimeter together to form a rectangle. The perimeter of the rectangle may be______ It could be______ ．

(1 + 12) × 2 = 26 (CM); (2 + 6) × 2 = 16 (CM); (4 + 3) × 2 = 14 (CM); answer: the circumference of this rectangle may be 26 cm, 16 cm or 14 cm. So the answer is: 14 cm, 26 cm, 16 cm

As shown in the figure, four identical rectangles are used to make a square. The circumference of each rectangle is 50 cm
What is the area of this square in square centimeters

(1) Four rectangles are arranged side by side so that the length of the rectangle is four times the width. Length: 20 width: 5 square area = 400
(2) A square is a special rectangle. If four are placed in the shape of "Tian", then the side length is 12.5 and the square area is 625

A rectangle, m meters long and 15 cm wide, what is its perimeter and area?

The perimeter is 30 × 2M and the area is 15m

There are two identical rectangular pieces of paper, 18 cm long and 15 cm wide, forming a large rectangle. What are the perimeter and area of the large rectangle?

The area is the same, 2 * 18 * 15 = 540 square centimeters, perimeter is 4 * 18 + 2 * 15 = 102 or 4 * 15 + 2 * 18 = 86
