area .please help

The area is 23.49 cm²

Step-by-step explanation:

Let us solve the question

In the given triangle

∵ The base of the triangle has a length of 8.7 cm

∴ The base = 8.7 cm

∵ The height of this base has a length of 5.4 cm

∴ The height = 5.4 cm

∵ The area of the triangle = × base × height

→ Substitute the values of the base and the height

∴ The area of the triangle = × 8.7 × 5.4

∴ The area of the triangle = 23.49 cm²

∴ The area is 23.49 cm²

Area of a triangle= 1/2 b×h

base= 8•7

height= 5•4

1/2× 8•7×5•4

Area= 23•49

~23•5

(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
