Question

A wire is bent in the form of square of side 8cm. if the wire is rebent as rectangle of width 5cm, then find the length of rectangle​

Answer 1

Step-by-step explanation:

Side of square = 8cm

.

Total length of square = Perimeter

Perimeter = 4×Side

Perimeter = 4×8cm

Perimeter = 32cm

.

As the same wire is again bent in the form of rectangle, the perimeter of square is equal to perimeter of rectangle.

.

Perimeter of rectangle = 2(l+b)

32cm = 2(l+5cm)

32cm = 2l + 10cm

32cm - 10cm = 2l

22cm = 2l

22cm ÷ 2 = l

11cm = l or length
