I posted this before can someone please check my answers and help me thanks:)
2 rectangles have equal areas determine the area of each rectangle then use this info to determine the perimeter.
rectangle one:
length of 2p + 3
width of 3.8
after my work i got p= 1.5
so the area is 14.4 and the perimeter is 19.6
is it correct?
rectangle 2 :
length of 6-p
width of 2.4
and im stuck on this one
can someone check my work for the first rectangle and help me on the second one, thanks :)
How did you get p from one rectangle? Odd.
If areas are equal
area1=area2
(2p+3)*3.8=(6-p)2.4
7.6p+11.4=14.4-2.4p
10p=25.8
p=2.58
To determine the area of each rectangle, you need to multiply the length by the width. Let's calculate the area of rectangle one:
Length = 2p + 3
Width = 3.8
Area of rectangle one = Length * Width
= (2p + 3) * 3.8
= 7.6p + 11.4
So, the area of rectangle one is 7.6p + 11.4.
Now, let's determine the perimeter of rectangle one. The perimeter is the sum of all the sides of the rectangle. Since we only know the length and width, we can calculate it using the following formula:
Perimeter = 2 * (Length + Width)
Substituting the values for rectangle one:
Perimeter of rectangle one = 2 * ((2p + 3) + 3.8)
= 2 * (2p + 6.8)
= 4p + 13.6
So, the perimeter of rectangle one is 4p + 13.6.
Now, let's move on to rectangle two:
Length = 6 - p
Width = 2.4
To find the area of rectangle two, multiply the length by the width:
Area of rectangle two = Length * Width
= (6 - p) * 2.4
= 14.4 - 2.4p
So, the area of rectangle two is 14.4 - 2.4p.
To determine the perimeter of rectangle two, again use the formula:
Perimeter of rectangle two = 2 * ((6 - p) + 2.4)
= 2 * (8.4 - p)
= 16.8 - 2p
So, the perimeter of rectangle two is 16.8 - 2p.
Now you have the areas and perimeters of both rectangles. Make sure to double-check your calculations and algebraic simplifications to ensure the accuracy of your answers.
