A rectangle has the length of 5x and the width of 5x-4. Find the perimeter and the area of this rectangle.
Filie reaserch what is this I don’t understand this how is my kid suppose to know this absolutely splended
To find the perimeter of a rectangle, you need to add up the lengths of all four sides. The formula for the perimeter of a rectangle is P = 2L + 2W, where P is the perimeter, L is the length, and W is the width.
Given that the length of the rectangle is 5x and the width is 5x-4, we can substitute those values into the formula:
P = 2(5x) + 2(5x-4)
Simplifying this expression, we get:
P = 10x + 10x - 8
P = 20x - 8
So, the perimeter of the rectangle is 20x - 8.
To find the area of a rectangle, you multiply its length by its width. The formula for the area of a rectangle is A = L * W, where A is the area, L is the length, and W is the width.
Using the given values, we can substitute them into the formula:
A = 5x * (5x-4)
Simplifying this expression, we get:
A = 25x^2 - 20x
So, the area of the rectangle is 25x^2 - 20x.
To find the perimeter of a rectangle, you add up the lengths of all four sides. In this case, the rectangle has a length of 5x and a width of 5x-4.
The formula for perimeter is: P = 2L + 2W, where P represents the perimeter, L represents the length, and W represents the width of the rectangle.
For this rectangle, the perimeter will be:
P = 2(5x) + 2(5x-4)
Simplifying further, we have:
P = 10x + 10x - 8
P = 20x - 8
So, the perimeter of the rectangle is 20x - 8.
To find the area of a rectangle, you multiply the length by the width. Again, using the values given, the area will be:
A = L * W
A = 5x * (5x-4)
Simplifying further, we have:
A = 25x^2 - 20x
So, the area of the rectangle is 25x^2 - 20x.
remember , Perimeter = 2 x width + 2 x length
area = length x width
Perimeter = 2(5x-4) + 2(5x)
= ....
area = 5x(5x-4)
= ...
in each case simplify my expression
