Answer: L=3, W=
Step-by-step explanation: Considering it is a rectangle
P = 2 (l+b) where L equals length and B breadth width)
10 = 2( L + (2/3×L)
Divide by 2
5= x + 2/3×x
5= x/1 + 2/3×x
5= x/1 + 2x/
expand the fraction to get the MCD
3x/3×1 + 2x/3
3x/3 + 2x/3
3x + 2x / 3
5x/3
5= 5x/3
multiply them by 3/5
3/5×5 = 3/5×5/3x.
cancel first 5s
3=3/5 × 5/3x.
cancel 3s
3= 1/5 ×5x
cancel 5s
3=x.
3 is length, so let's add everything up.
p = 2.(l+b)
10= 2. (3+b)
Divide this by
5=3+x
highlight the x by changing order of the numbers.
-x=3-5
-x = -2
then multiply by (-1) to make them positive:
x=
Therefore, length is 3 and width is 2.
