Question

The perimeter of a rectangle is 124 inches. The length exceeds the width by 10 inches.

what is the length in inches?
what is the width in inches?

Answer 1

26 and 36

Answer 2

let widht be x
let lenght b (x+10)

finally

2(l+ b) = 124

Answer 3

perimeter of a rectangle is 2x + 2y = 124
y = w + 10
substitute
2x + 2 (x + 10) = 124
solve for x. Use x to back substitute for y
2x + 2x + 20 = 124
4x = 104
x = 26
y = 36
check 26*36 = 124 i hope

Answer 4

2 [x+10(x)]

2 [x^2 + 10x] = 124

Answer 5

a+b = 62 and a-b = 10 => a=36, b = 26

Answer 6

so length is 36 and width is 26?

Answer 7

yes!

Answer 8

thank you all
