what is the area of this figure?

enter your answer in the box.

__m²

81 m².

Step-by-step explanation:

We are given that,

The figure contains a right angled triangle and a parallelogram.

Dimensions of the triangle is: Base = 9 m, Height = 8 m.

Dimensions of the parallelogram is: Base = 9 m, Height = 5 m.

So, in order to find the total area, we will add the area of the two individual figures.

Area of triangle = =   = 9 × 4 = 36 m²

Area of parallelogram = Base × Height = 9 × 5 = 45 m².

Thus, the total area of the figure = 36 + 45 = 81 m².

Hence, the required area is 81 m².

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
