Step-by-step explanation:
The length and width of the rectangle is 362 m and 272 m respectively.
Step-by-step explanation:
Let the length be "x m".
then the width = x - 90 m
Perimeter = 2 x (length + width) ------------------------------(1)
Substituting Length and width value in the above equation (1), we get,
2 x (x+x-90) = 1268
or, 2x - 90 = 1268/2
or, 2x - 90 = 634
or, 2x = 634 + 90
or, 2x = 724
or, x = 724/2
= 362
Thus the length = 362 m
width = 362 - 90 m = 272 m
Answer:
A =256 mm^2
Step-by-step explanation:
The perimeter of a square is given by the formula
P = 4s where s is the length of a side
64 = 4s
Divide each side by 4
64/4 =4s/4
16 = s
To find the area of a square, use the formula
A =s^2
A = 16^2
A =256 mm^2
