Suppose you know the area of the yard is 7,500 square feet. How can you find the value of a? —help and it comes with a picture

a = 50

Step-by-step explanation:

From the introduction, you know that the area is 3a^2

You also know that it is 7500 square feet. \

So the two must be equal

3a^2 = 7500                    Divide by 3

a^2 = 7500/3

a^2 = 2500

The square root of 2500 is 50

sqrt(a^2) = sqrt(2500)

a = 50

the discriminant is 64 + 4*1*12 = 112

this is prime.
