Question

The perimeter of a rectangle is 30 ft. The length is four times the width. find the length and width of the rectangle.

Answer 1

30= 2(4x+x)
30= 8x+2x
30=10x
x=3
width=3
lenght=12

Answer 2

2(4x + x) = 30
2(5x) = 30
10x = 30
x = 3

So, LENGTH = 12
BREADTH = 3

Answer 3

Perimeter of a rectangle = 2(a + b)

Answer 4

First step,

suppose,
width = x
Length = 4x

now you will understand.
