Question

Write the simplified expression for the rectangle's perimeter.

10x is the width
8x + 5 is the length

Answer 1

Finding x

8x+5 = 10x

8x-10x=-5

-2/-2= -5/-2

x= 5/2

Length

8x+5

8(5/2)+5

40/2+5/1

20+5

L=25

Width

10x

10(5/2)

50/2

W=25

Perimeter= (length+width)×2

2(l)+2(w)

2(25)+2(25)

50+50

P=100

Explanation:

Rectangles do have two equal lengths and two equal widths but the value of x when I plug it in does give the same value which is supposed to be square due to the square having 4 equal sides
