Answer:

9 x 20ft = 180

If one of those values 8ft and 20ft is the diagonal then we deduct the square of thise numbers being  √400 -   √81 =  √309 and find  √309 square of  17.57ft

17.57 x 9 = 158.13

so  √158.12 = 12.57

and  √162 = 12.72

But your question was just a case of finding how to do area and for that we use L x W to find area

A = 9 x 20 = 180ft^2

Answer:

smaller x =-1/2

larger x = 7

Step-by-step explanation:

(x-7)(-4x - 2) = 0

Using the zero product property

(x-7)=0              (-4x - 2) = 0

x-7+7 = 0+7        -4x-2-2 =0+2

x=7                         -4x =2

                               -4x/-4 = 2/-4

                                    x = -1/2
