Answer:
Step-by-step explanation:
The total area = 8 * 10 = 80 sq meters
The blue area = x^2
The left over part is 80 - x^2
So the question is what is the value of x that makes x^2 > 80 - x^2
x^2 > 80 - x^2 Add x^2 to both sides
x^2 + x^2 > 80 Combine
2x^2 > 80 Divide by 2
x^2 > 80/2
x^2 > 40 Take the sqr root of both sides.
√x^2 > √40
x > 6'32
