Question

c) A thin wire 20 centimetres long is formed into a
rectangle. If the width of this rectangle is
4 centimetres, what is its length?​

Answer 1

Answer:

The wire has formed the perimeter of rectangle. As such,

Petimeter of Rectangle = sum of all sides

As the length of wire was 20 cm, therefore the perimeter of rectangle is 20 cm.

Perimeter of rectangle =2 (length + width)

2 (Length + 4) = 20

Length + 4 = 20/2

Length + 4 = 10

Length = 10 - 4

Length = 6 cm.

Length of formed rectangle is 6 cm.

Answer => Length of formed rectangle from

wire is 6 centimeter.

Answer 2

Answer:

6cm

Step-by-step explanation:

2l=20-(2×4)=12

2l= 12= l= 12/2= 6cm
