Question

A rectangular plate has area 48 m². Its length is 2 m greater than its breadth. What are its dimensions?

G1 Physics · Accepted Answer

Let breadth=x m, so length=x+2 m. Area gives x(x+2)=48 ⇒ x²+2x−48=0=(x−6)(x+8). Thus x=6 or −8. A physical length cannot be negative, so breadth=6 m and length=8 m.
