Pls answer 7 no

Pls answer 7 no original number. Find the original number. 7. The length of a rectangle is one and half times its breadth. If the perimeter of the • rectangle is 100 cm. find the length and the breadth of the rectangle. 8. The ratio of the preser 11 1

Let the breadth be x
then length = 3x/2
so
2(x+3x/2)= 100cm.
2(5x/2)= 1000
5x= 100
x = 20 cm.

so . breadth = 20cm.
and length = 30 cm.
