Answer:
- Length of diagonal 1: 8 meters
- Length of diagonal 2: 10 meters
Step-by-step explanation:
Let d1 be the first diagonal and d2 be the second diagonal.
Given
Area = 40 square meters
And one diagonal is 2 meter longer than other
The formula for area of kite is;
Putting the known values
The expression is a quadratic polynomial
Factorizing
As the value of length cannot be negative so discarding the negative value
Hence,
- Length of diagonal 1: 8 meters
- Length of diagonal 2: 10 meters
