Question 1 A=lw for l=6, w=12 A=?

question 2 d=rt for r=25, t=11 D=?

(For the first question)

When you have two variables next to eachother, that means to multiply.  So that's the same as

They give that  and

So now you plug  and  into the equation:

If you multiply  you get

So your final answer is 72!

Sorry that i couldnt answer the second one, i hope this helped!! Pls give brainliest :>

Have a nice day!! :D

Question 1: Area=72 units

Question 2: D=275 units

Step-by-step explanation:

For question 1, you multiply the length, which is 6, by the width, which is 12 and you get 72 as your area. For question 2, you multiply 25 by 11 to get D.

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
