Question

The perimeter of a rectangel is 13cm qnd its width is 3,2,4 cm. find its lengths

Answer 1

Width = 11/4 cm

Let the length be a

Perimeter = 2 ( a + 11 / 4)

=> 13 = 2 ( 4a + 11) / 4

=> 13 = (4a + 11) / 2

=> 4a + 11 = 26

=> 4a = 15

=> a = 15 / 4


Length = 15 / 4 cm

$length \: = 3 \frac{3}{4}$
