What is the sum of first k+1 even numbers

Step-by-step explanation:

Given

k + 1 even numbers

Required

Their sum

This question will be solved using the sum of nth term of an AP

Where

a = the first even number

n = number of terms

d = difference between consecutive even numbers

So, the expression becomes:

Factorize 4 + 2k

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
