I need help solving this pls help

37ft²

Step-by-step explanation:

area of traingle= 1/2★ base★height

base= 1.5+1.5+4 = 7ft

height= 6ft

so area of traingle= 1/2★7★6 = 21ft²

area of square= side★side

side of square= 4ft

so area of square= 4★4= 16ft²

total area of shape= area of traingle + area of square

= 21+16

= 37ft²

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
