Sample Questions and Discussion Wide Rectangle

Sample Questions and Discussion Wide Rectangle - Rectangle is a flat wake consisting of two pairs of sides of equal length and parallel. Measuring at a long side is referred to as the length (p) of the rectangle while the short side will be referred to as the width (l) of the rectangle. Previous Mathematical Formulas Basic've never given an explanation of How to Calculate Wide Formula Rectangle and Example Because in this post is added again some examples matter and consideration of the area of ​​a rectangle to deepen your understanding of how to solve problems relating to the area of ​​a rectangle surrounding material. Let's refer to direct the discussion:

Example Problem 1:
A tablecloth rectangle with a length of 90 cm and a width of 60 cm. what is widely tablecloth ?

Resolution:
Given: rectangular, length (p ) = 90 cm, width (l) = 60 cm
Asked: Size (L)
Answer: L = p X l = 90 cm X 60 cm = 5400 cm 2
Thus, extensive tablecloth is 5400 cm 2


Example Problem 2:
space hall rectangular. Its length of 25 m and a width of 12 m. How m 2 -kah the spacious hall?

Resolution:
Given: rectangular, length (p) = 25 m, width (l) = 12 m
Asked: Size (L)
Answer: L = p X l = 25 m X 12 m = 300 m 2
Thus, the vast hall is 300 m 2


Example Problem 3:
Desi has a garden with an area of ​​32 m 2 . If the length of the park 8 m, what is the width of the park?

Resolution:
Given: rectangular Size (L) = 32 m 2 the length of the park (p) = 8 m
Asked: wide garden (l)
Answer: l = L: p = 32 m 2 : 8 m = 4 m
Thus, the width of the park it is 4 meters.


Example Problem 4:
Mira has an area of ​​30 m 2 it will be fitted room floor tile measuring 30 cm X 20 cm. How many pieces of ceramics required for the floor of the space?

Resolution:
Given: area of ​​room = 30 m 2
Size ceramics: length (p) = 30 cm, width (l) = 20 cm
Asked: Number of ceramics required

Answer: Size of ceramic (L) = pxl = 30 cm x 20 cm = 600 cm 2
area of ​​room = 30 m 2 = 300.000 cm 2
Number of ceramics = 300,000 cm 2 : 600 cm 2 = 500 pieces
So, lots of ceramics required for floor space ters ebut is 500 pieces.


Sample Problem 5:
Yuni buy fabric measuring 4 m 2 . If the width of the fabric 160 cm, how many meters long cloth?

Resolution:
Given: rectangular Size (L) = 40 m 2 = 40000 cm 2 the width (l) = 160 cm
Asked: length (p)
Answer: p = L: l = 40000 cm 2 : 160 cm = 250 cm = 2.5 meters
Thus, the length of fabric purchased Yuni adalaha 2.5 meters


that's some Sample Size Problem and Discussion Rectangle that you can learn to understand how to solve similar problems. Semogakalian can understand it well. See you on the discussion of other matters.

You'll often see at the supermarket or supermarket there are a lot of rebates or discounts, it is an example of a rebate. If you are curious about how to calculate the price cuts, the Mathematical Formulas Basic will give his review to you through examples to the following: Example Problem Discussion and Arithmetic Social About Rabat Example Problem 1 Melly want to buy a dress for Rp 120,000. It turned out that the clothes receive a rebate of 20%. What is the size of the rebate? Answer: clothes Price: Rp 120,000 Rabat: 20% x 120,000 = 20/100 x 120,000 = 24,000 Thus, rabatnya amounted Rp.24.000 Example Problem 2 [1945901million] A Shop, gives a 5% discount for every purchase math book.
