Find perimeter of rectangle when length = 4.6m and breadth = 360cm​
ivann1987 [24]

Answer:

16.4 m²

Step-by-step explanation:

length = 4.6 m

breadth = 360 cm = 360 ÷ 100 = 3.6 m

Perimeter = 2*(l + b)

                 = 2 * ( 4.6 + 3.6)

                 = 2 * 8.2

                  = 16.4 m²

Assign two variables for each problem, and write the equations. Do not solve.
GalinKa [24]
Call the amount of pineapple "P', and the amount of gingerale "G".

We know that a mix of pineapple and gingerale makes 200 cups. So: 
P+G=200

We also know that double the pineapple (i.e. 2P) and triple the gingerale (i.e. 3G) makes 420 cups. So:
2P+3G=420

We can now solve by substitution:
2P+3(200-P)=420
2P+600-3P=420
-P=-180
P=180

180+G=200
G=20

For 420 cups we need 2P=360 cups of pineapple and 3G=60 cups of gingerale]
