Answer:

$426.96 \: {km}^{2}$

Step-by-step explanation:

Area of the shaded region = Area of triangle with base 40 km and height 27 km - Area of circle with radius (12/2) 6 km.

$= \frac{1}{2} \times 40 \times 27 - 3.14 \times {(6)}^{2} \\ \\ = 20 \times 27 - 3.14 \times 36 \\ \\ = 540 - 113.04 \\ \\ = 426.96 \: {km}^{2}$

Find the rate of interest per annum at which ₹ 5000 will amount to ₹ 6, 050 in 3 years.

loris [4]

Answer:

Step-by-step explanation:

Using the formula

Amount = Principal + Interest

Give the following

Principal = ₹ 5000

Amount =₹ 6050

Time = 3 years

Required

Time

Substitute into the formula

A = P + I

A = P + PRT/100

6050 = 5000 + 5000(R)(3)/100

6050 - 5000 = 150R

1050 = 150R

R = 1050/150

R = 7

Hence the rate of interest is 7%
