A wire, whose length is atmost 62 cm is bent to form a rectangle. If the length of the is 7 cm larger than the width, what is the maximum area of the rectangle?

Sagot :

Manelviz
P= 2L+2W
62= 2(x+7) +2x
62= 2x+14+2x
4x= 62-14
4x= 48
 x=12

To find the area, use the formula A=lw
 A= (19) (12)
A= 228 [tex] cm^{2} [/tex]
