Find the x intercept of the line from substituting y=0, then find the y intercept of the line from substituting x=0 then draw a line connecting these two points
Answer:
Length = 3 cm
Width = 1 cm
Step-by-step explanation:
Let the length of rectangle be l and width of rectangle be w.
According to problem,
l = 3w {Length of rectangle is equal to triple the width}
And Perimeter,P = 8 cm
Since, P = 2 ( l + w )
or 8 = 2( l + w)
Plug l =3w in the above perimeter equation.
We get:
8 = 2( 3w + w)
8 = 2(4w)
8 = 8w
or w = 1 cm
Then length ,l = 3w =3 * 1 = 3 cm
Hence length of rectangle is 3cm and width of rectangle is 1cm.
If angle AED is 90 degrees and angle AEB is 60 degrees. Subtract 60 from 90. Since BEC and CED are equal, the difference of 60 minus 90 (30) divided by two is the sum. 60 + 15 +15 = 90. BEC and CED equal 15 degrees. Good luck.
Diagonals of a rect. are equal...
diagonals bisect each each other...
from these two properties we get ,
4x-12 = 1/2 (7x-18)
2 (4x-12)=7x-18
8x-24=7x-18
x=6
