Answer 1

Answer:

HEY MATE!!! HOPE THIS HELPS YOU.

Step-by-step explanation:

Let the breadth of a rectangle be x.

So length of rectangle will be 4x.

Perimeter of rectangle = 2(l+b)

                               100 =2 (4x+x)

                               100 = 2 × 5x

                               100 = 10x

                                 $\frac{100}{10}$ = x

                             10cm = x

Breadth of rectangle = 10cm

Length of rectangle = 4 × 10 = 40cm
