A rectangular lawn is 2 m longer than it is wide. The area of the lawn is 21 m². The gardener wants to edge the lawn with edging strips
which are sold in lengths of 13 m. How many will she need to buy?

Let's breadth be x

ATQ

Now

Total strips

• width is y metres

• length is (2 + y) metres

• Therefore, length = 4 + 2 = 6 meters

• The gardener will need;

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
