The school sports ground of rectangular shape has a width of 90 m and an area of 11250 m2.

The school sports ground of rectangular shape has a width of 90 m and an area of 11250 m2. Find the length of the sports area?

To solve this problem, we first need to remember the rule for finding the area of a rectangle:

S = a * b, where

S – area;
a – length;
b – width.

Then to find the length, we get the following formula:

a = S: b.

Now we substitute the data from the problem statement: S = 11250, b = 90, then

a = 11250: 90

a = 125

125 m length of the sports ground.

Answer: 125 m.
