Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = $\frac{1}{2}$ h(a + b)

where h is the height and a, b the parallel bases

Here h = 9, a = 13 and b = 17 , thus

A = $\frac{1}{2}$ × 9 × (13 + 17)

= 0.5 × 9 × 30

= 135 cm²

The annual income of Sam is Rs 43,360. What is his monthly income if he earns an equal amount every month?

tankabanditka [31]

His monthly income if he earns an equal amount every month is Rs 3,613.33

<h3>How to determine the monthly income?</h3>

The annual income is given as:

Annual income = Rs 43,360

The monthly income is calculated as

Monthly income = Annual income/Number of months

There are 12 months in a year

So, we have:

Monthly income = Rs 43,360/12

Evaluate the quotient

Monthly income = Rs 3,613.33

Hence, his monthly income if he earns an equal amount every month is Rs 3,613.33
