The perimeter of parallelogram is 72 meters. The width of the parallelogram is 4 meters less than its length . Find the Length a
Marrrta [24]
Let n = length
let n-4 = width since it is 4 meters shorter

2( n+n-4)  =72  Two of the length and width added together equal the perimeter
combine like terms
2(2n -4) = 72   Now use the distributive law on the left side of the equation
4n -8 = 72    Now add 8 to both sides

4n -8 +8 = 72 +8
4n = 80  Finally divide each side by 4
n=20
so the length is 20 and the width is 4 less or 16.
Let's see if our answer works.
20 + 16 + 20 +16 =?  72
 72 =72  yes, it does.   Length = 20 Width = 16

Identify the perimeter of a rectangle in which h = 8 ft and a = 144x ft^2. please help asap
Blababa [14]

Here, Given

h= 8ft

a=144 * ft^2

then,

A=L*H

144=L*8 or 144/8 =L

L=18

now, P=2(L+H)

P=2(18+8)

P=52m

Perimeter and area are two important and basic mathematical subjects. They help quantify the physical space and also provide a more advanced foundation of mathematics in algebra, trigonometry, and calculus. Perimeter is a measure of the distance around a shape, and area indicates how much area the shape covers.

The perimeter of a 2D shape is the distance around the shape. You can imagine wrapping a string around a triangle. The length of this cord is around the triangle. Or, if you're traveling outside the park, take a route that goes around the edge of the park.
