Hey

Here is your answer,

Perimeter of a triangle = 13 cm

Width = 11/4 cm

Length = x

2 ( l+b ) = 13

( l+b ) = 13/2

X = 13/2 - 11/4

X = 52 - 22 / 8

X = 40 / 8

X = 5

Hope it helps you!

Answer 2

Perimeter of rectangle = 13

2 ( Breadth + Length )= 13

2 ( 11/4 + x ) = 13

2( 11 + 4X ) = 13 × 4

11 + 4x = 13 × 4/2



11 + 4x = 26

4X = 26 - 11

4x =15

X = 15/4 cm
