Question

A rectangle has a width of 55 centimeters and a perimeter of 224 centimeters. What is the rectangle's length

The length is
cm.

Answer 1

`as \: we \: know \: perameter \: of \: rectngle = 2(length \ + beadth)`

`and \: also \: perimeter \: = 224cm`

`therefore \: we \: can \: write \: that 2(length + bredth) = 224cm`

let the length be l

and breadth is 55 cm

`2(l + 55) = 224`

`l + 55 = (224)/(2)`

`l + 55 = 112`

`l = 112 - 55`

`l = 57`

so the length of rectangle is 57 cm
