Hello,
sin(-45°)=-√2 /2 =-0,7071067....
Answer:
2340 ft^2
Step-by-step explanation:
Assume the width to be...x
then the length to be....x + 7
Perimeter = 2(x)+ 2(x + 7)....lm multiplying by two because there is two sides(length and width)
;194 = 2x + 2x + 14
; x(width) = 45ft
then the Area = 45 × (45 + 7)
;AREA = 2340 ft^2
