Question

The length of a rectangle is twice it's width. If the perimeter is 24cm. Calculate it's area

Answer 1

Answer:32cm

Step-by-step explanation: Length; 4cm

                                           Breadth;8cm

area= lxb

       = 4X8

       =32cm

Answer 2

Answer:128$cm^{2}$

Step-by-step explanation:let width=b

therefore length will be 2b

ATQ. b+2b=24

=>3b=24

=>b=8

so the width is 8cm and length is 2x8cm=16cm

and the area is=8cmx16cm=128$cm^{2}$
