Answer:

The answer is 40.8 m.

Step-by-step explanation:

To find the perimeter of the rectangle, use the formula P= 2(l)+ 2(w). Plug in the information given in the question, and the equation will look like

P= 2(12m) + 2(8.4m)

Solve the equation, and the final answer will be 40.8 m.

OlgaM077 [116]

Answer:

4 apples are $2.40

That means that 2 apples will be $1.20

And that one apple will be $0.60

$0.60*9= $5.40

She buys 5 more apples each week so she will buy 14 apples this week

$0.60*14= $8.40

Final answer : She will buy 14 apples next week for $8.40

Hope it helped! : )

Here's the question ​
zheka24 [161]

Answer:

60

Step-by-step explanation:

perimeter (p) = 8 + 17 + 15 = 40

semi-perimeter (s) = p/2 = 20

Area = square root of s(s-a)(s-b)(s-c) where a,b,c are the sides of the triange by Herons formula.

Therefore, area = 20(20-8)(20-15)(20-17) = square root of 3600 = 60
