Answer: 27cm²

Step-by-step explanation:

lets take the width as x and length as 3x( since length is 3 times the width)…

Perimeter of the rectangle is 24 cm( 2*(l+b))= 2×(3x+x):24

2×4x=24

8x=24

X( width): 24/8=3cm

Length= 3x: 3*3=9cm

Area of the rectangle: ( l*w)= 9×3: 27cm²

Solve for u. 15u − 12u = 15

Leno4ka [110]

15u - 12u = 5

First combine like terms

3u = 5

Then isolate the variable by dividing both sides by 3

u = 5/3

u = 1 2/3

Hope this helped!

Corlos bought a book for $9 . now he would like to buy 4 other books for the same price .how much will he have to pay in all for

Rashid [163]

I'd do 9x4=36 because the 9 is from your money and the 4 is from your books. Now since you want to find out how much 4 books cost you just multiply that by 9
