Answer:

140 feet

Step-by-step explanation:

You will need to find the perimeter of the backyard to find how many feet of fencing will be needed

the formula for perimeter is: 2l+2w

So 2 times 30 is 60

with 2 times 40 80

60+80 is 140

Thus you will need 140 feet to cover the backyard

Hope this helps!

lakkis [162]

Answer:

£6

Step-by-step explanation:

Let

Plain scones = x

Cheese scones = 3x

Fruits scones = 4(3x)

= 12x

Total price of scones = £96

She sells each scone for the same price.

Total price of scones = Plain scones + Cheese scones + Fruits scones

96 = x + 3x + 12x

96 = 16x

Divide both sides by 16

x = 96/16

= 6

Plain scones = x = £6

Cheese scones = 3x

= 3(6)

= £18

Fruits scones = 4(3x)

= 12x

= 12(6)

= £72

How much does she make from the sale of the plain scones?

She made £6 from the plain scones
