What is the area of this composite shape? Enter your answer in the box. in²

Area = 53 in²

Step-by-step explanation:

area of a box = 8 * 6 = 48 in²

area of a triangle = 1/2 * b * h

b = 6 - 4 = 2 in

h = 13 - 8 = 5 in

area of a triangle = 1/2 * 2 * 5 = 5 in²

total area = area of a triangle + area of a box

total area = 5 in² + 48 in²

total area = 53 in²

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
