Answer:
1 2/21
Step-by-step explanation:
We start out with:
3/7 + 2/3
In order to add them together, they must have an equal denominator. An easy way to find an equal denominator is the cross method. We divide 7 by 3 and 3 by 7, giving us a denominator of 21:
3/21 + 2/21
But what about the numerators? You do the same thing as before (multiplying by the other's denominator). Now we have:
9/21 + 14/21
We add both together (the denominator stays the same) and we get 23. 23/21 is correct but not in simplest form. We remove 21 from the numerator (because it is a whole) and finally get:
1 2/21!

Length of the rectangle is 40 meters.
Step-by-step explanation:
- Step 1: Ratio of width:length = 4:5, so let width be 4x and length be 5x. Find the length if area = 2000 sq. m
Area of the rectangle = length × width
2000 = 5x × 4x
2000 = 20x²
⇒ x² = 2000/20 = 100
∴ x = 10
4x = 40 m
