<h3><u>A</u><u>n</u><u>s</u><u>w</u><u>e</u><u>r</u><u>:</u><u>-</u></h3>

Let

  • Width of rectangle=x
  • Length of rectangle=2x
  • Perimeter=432cm

We know that in a rectangle

☆ Perimeter=2(Length+Breadth)

\\ \sf\longmapsto 2(x+2x)=432

\\ \sf\longmapsto 2x+4x=432

\\ \sf\longmapsto 6x=432

\\ \sf\longmapsto x=\dfrac{432}{6}

\\ \sf\longmapsto x=72

\\ \sf\longmapsto 2x=2(72)=144

  • Length=144cm
  • Breadth=72cm

☆Area=Length×Breadth

\\ \sf\longmapsto Area=144\times 72

\\ \sf\longmapsto Area=10368cm^2

brilliants [131]

Answer:

Step-by-step explanation:

One of the most important things to understand about lines is the definition of slope. Slope is the 'steepness' of the line, also commonly known as rise over run. We can calculate slope by dividing the change in the y-value between two points over the change in the x-value.
