The length of a rectangle is 26 units less than its width. Ifs is the rectangle's width, then its area is a (x-26)x
b 2(x+13)
c x(x+26)
d x(26x)
e 2(x-13)
f No Answer

Option a, (x-26)x

Step-by-step explanation:

Length is 26 units less than its width, let the length be x, so the width is x+26, so it's area will be their multiplication,

x(x+26)

since the formula to find area is (length×width)

However thing to note, if you assume the width to be x, the the length will be (x-26), so here the area becomes (x-26)x

since here the length is less than width, (x-26)x is the answer we will use.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
