Q2. Calculate the area of the shaded region in the figure shown.
40°
12m
10m​

Area of the shaded area = 60 m^2

Step-by-step explanation:

Remark

I don't think you need the 40 degrees for anything.

Formula

Area of Shaded part = area of the rectangle - area of the triangle

Solution

Area of the Rectangle

L = 12 meters

W = 10 meters

Area = 12 * 10

Area = 120 m^2

Area of the triangle

Area = 1/2 b * h

b = 12

h = 10

Area = 1/2 * 12 * 10

Area = 120/2 = 60

Area of the shaded area

120 - 60 = 60

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
