The area of a rectangle is L x W or A = w l.
Given: six rectangles with the lengths of 1,4,9,16, 25, and 36
all six has the base width of 2
Let all 6 rectangles be, R1, R2, R3, R4, R5, and R6
R1
R1=L x W
= 1 x 2
R1 = 2
R2
R2 = L x W
= 4 x 2
R2 = 8
R3
R3 = L x W
= 9 x 2
R3 = 18
R4
R4= L x W
= 16 x 2
R4 = 32
R5
R5 = L x W
= 25 x 2
R5 = 50
R6
R6 = L x W
= 36 x 2
R6 = 72
Total sum of areas = R1+ R2 + R3 + R4 + R5 + R6
= 2 + 8 +18 + 32 + 50 + 72
Total sum of areas = 182
