Question

The perimeter of a rectangle is equal to that of a square with side 16 m if the rectangle is 12 m wide what is its length

Answer 1

Given
Side of a square=Perimeter of a Rectangle=16cm
Width of a Rectangle=12cm

Perimeter of a Rectangle=16cm
2(l+b)=16cm
2(l+12)=16
2l+24=16
2l=24-16
2l=8
l=8/2
l=4cm

Hence, The length of the Rectangle is 4cm.
