all you have to do is add together the four sides. 2L+2W=Perimeter (L=length or base, W=Width or height)
To find the height of the rectangle, we can use the formula for the perimeter ( P ) of a rectangle, which is ( P = 2 \times (\text{base} + \text{height}) ). Given that the perimeter is 38 and the base is 7, we can set up the equation: ( 38 = 2 \times (7 + \text{height}) ). Simplifying gives ( 19 = 7 + \text{height} ), leading to ( \text{height} = 12 ). Thus, the height of the rectangle is 12.
2*(base) + 2*(height) = perimeter
increase
If you mean a 3 inches by 4 inches rectangle then its perimeter is 14 inches
It is: perimeter minus hypotenus+base = height Area = 0.5*base*height
Height = (Perimeter/2) - Base

2 x base + 2 x height= perimeter
If you mean a 3 inches by 4 inches rectangle then its perimeter is 14 inches
It is 36 units.
44.3 mm
It is: perimeter minus hypotenus+base = height Area = 0.5*base*height
Height works out as: 33.7 mm Check: 2*(33.7+71.4) = 210.2 which is the perimeter
Well, the area of a rectangle is "base*height"You need to find the height in order to find the perimeterYou need to substitute everything you need to know in the area formulaEx: base=5 area=205*h=20Now you need to simplify the problemEx: h=4So now we know that the height is 4The perimeter formula is (2*base)+(2*height)Ex: (2*5)+(2*4)10+8Perimeter = 18
