Suppose base and height are b and h. 2b+2h=44 (the perimeter includes two bases and two widths) b=2b-11 base is 11 less than two times base Subtract b from both sides: 0=2b-11-b, b-11=0, b=11 2b=22 2b+2h=44, 22+2h=44, 2h=44-22=22, h=11 So the rectangle is a square with side 11.
2 times (length + width)
30cm
40 meters.
The perimeter of a rectangle is the distance around the rectangle. The area of a rectangle is the space inside the rectangle. To calculate either one you need the length and the width of the rectangle. To calculate the area multiply the length times the width. To calculate the perimeter add the length+width+length+width (that is the distance all the way around)
The relationship between the area of a triangle and a rectangle is a Triangle is base times height divided by 2. Area of a rectangle is length times height.
Assuming that this question should have read, "The perimeter of a rectangle is 38m. The base is four more than two times the height. What is the height?", the answer can be obtained as follows: The perimeter of a rectangle is the twice the sum of its base and height. Call the unknown height h. Then, from the problem statement, 2[h + (2h + 4)] = 38. Expanding and collecting like terms gives 6h = 30 or h = 5 m.
That would be 3 x 9 inches.
30cm
2 times (length + width)
5mm is NOT TRUE You find it by dividing it by 2
(I am assuming that you mean 134.2.) To find a perimeter of a rectangle, you multiply the measurement of the base by 2, and add it to the measure of the height that is multiplied by two. So work backwards, 45.3cm times 2 is 90.6cm. 134.2cm-90.6cm=43.6cm. So the height is 43.6 cm. Wrong! you have to divide 43.6 by 2 to get height. It would be 21.6cm
Perimeter of a rectangle = 2*(H+W) = 2*(11+22) = 2*33 = 66 inches.
Area: rectangle length times width Area: triangle 1/2base times height Area: trapizoid 1/2 (base1 plus base2) perimeter add up the sides
It is not. The perimeter of a 1 cm square is 4 cm. The perimeter of a 5 km * 15 km rectangle is 4000000 cm: a million times as large!
The area is the length times the width. The perimeter is two times the length plus two times the width.
40 meters.
Area is length times width, perimeter is twice the sum of length and breadth.
