Question

The length of a rectangular sheet of paper is five times its breadth. If the area of the sheet is 1,445 sq.cm, find the length of the sheet.

Answer 1

Step-by-step explanation:

length=5y

breadth=y

5y X y=1445

5y2( square)=1445

y2=1445÷5

y2= 289

y=

$\sqrt{289}$

y=17

length= 5x

length= 5x17

length=85cm
