So first, we have to get the area of each rectangle, in which the formula is A = (l)(w), where l is the length and w is the width.
Rectangle having the length of 1: A = (1)(2) = 2
Rectangle having the length of 4: A = (4)(2) = 8
Rectangle having the length of 9: A = (9)(2) = 18
Rectangle having the length of 16: A = (16)(2) = 32
Rectangle having the length of 25: A = (25)(2) = 50
Rectangle having the length of 36: A = (36)(2) = 72
2+8+18+32+50+72 = 182
Therefore, the answer is 182.
