The area of the square is  900cm²

The perimeter of a square is 120 cm

Left the side of the square = a

Eachsides ofthe  square is =4a

The perimeter of a square is square root 120cm.

4a = 120.

 a = 120 / 4 = 30.

Area = a² = 30² = 900cm².

<h3>What is perimeter?</h3>

The perimeter of a shape is defined as the total distance around the shape. Basically, the perimeter is the length of any shape when expanded linearly. The circumference is the total distance that the shape covers in the 2d plane. Circumferences of different shapes can be equal in length  depending on their dimensions.

The coffee Lily likes is composed of 97.3% water and 2.7% cocoa. The coffee John likes is composed of 96% water and 4% cocoa. Ho
mestny [16]

30 ounces of the coffee John likes consists of

  • 0.96\cdot30=28.8 ounces of water
  • 0.04\cdot30=1.2 ounces of cocoa

To this mixture we're adding x ounces of water, so that the new mix has a total volume of 30+x ounces and matches the composition of the coffee Lily likes. This means it would consist of

  • 0.973\cdot(30+x)=28.8+x ounces of water
  • 0.027\cdot(30+x)=1.2 ounces of cocoa (same amount of cocoa as before because pure water is being added)

Solve for x:

0.973(30+x)=28.8+x\implies29.12+0.973x=28.8+x

\implies0.39=0.027x

\implies x\approx14.4

###

Just to confirm: the new mixture consists of

  • 28.8+14.4=43.2 ounces of water
  • 1.2+0=1.2 ounces of cocoa

giving a total volume of 43.2+1.2=44.4 ounces of coffee, and \dfrac{43.2}{44.4}\approx0.973, as required.
