Answer:

First side is: 12cm

Second side is: 36cm

Third side is: 16cm

Step-by-step explanation:

Let x represent the shorter side

Then 3x represents the second side, and

x + 4 represents the third side.

Perimeter of three sides:

P = x + 3x + (x + 4)

Perimeter is 64, so

64 = x + 3x + (x + 4)

64 = 5x + 4

60 = 5x

12 = x

First side is x: 12cm

Second side is 3x: 3(12) = 36cm

Third side is x + 4: 12 + 4 = 16cm

5. A piece of plywood has a length that is 5 more than twice its width. Write the expression that represents the area of the ply
Sholpan [36]
5w^2 = A
 
You would multiply the width (w) by 5 because it's 5 times more than twice it's width. Then w (Width) would be to the power of 2 because it's 5 times more than twice its width. And this will all equal the Area (a)

Find the length of the rectangle with a perimeter of 200 cm and breadth of 10 cm.
Rudiy27

Step-by-step explanation:

Given,

Perimeter of the rectangle = 200cm

Breadth of the rectangle = 10 cm

Therefore, by the problem

=> 2(l+b) = 200cm

=> 2(l + 10) = 200cm

=  > l + 10 =  \frac{200}{2}

=> l + 10 = 100

=> l = 100 - 10

=> l = 90

<u>Hence, required length othe rectangle is 90 cm (Ans)</u>
