Answer 1

see
perimeter of a rectangle = twice the sum of length and width
=> perimeter of a rectangle = 2(length + width)
since you are given perimeter and width, the above equation gives the value of length on solving
once you obtain length

area = length*width

Answer 2

2 L + 2 w = 122
2 L + 50 = 122
L = 36
A = 36 * 25 = 900 square inches
Ceiling[900/144] = 7 square feet to the next whole square foot.
Ceiling[900/(144*9)] = 1 square yard to the next whole square yard
