The total area of the composite figure will be equal to 488 square meters.
The space occupied by any two-dimensional figure in a plane is called the area. Here we have two figures a rectangle and a right-angle triangle.
We have the following data:-
Total area = Area of rectangle + Area of triangle
Total area = (L x W) + (1 / 2)[ B x H]
Total area = ( 22 x 17 ) + (1 / 2)[ 12 x 19 ]
Total area = ( 374 + 114 ) = 488 sq2uare meters
Therefore the total area of the composite figure will be equal to 488 square meters.

Answer:
4.200
Step-by-step explanation:
Change the divisor 0.9 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.
We then have the equations:
37.8 ÷ 9 = 4.200
and therefore:
3.78 ÷ 0.9 = 4.200
Both calculated to 3 decimal places.
The division of 3.78 by 0.9 equals 4.2 after rounding to the nearest tenth. The given problem is an arithmetic division question typically encountered in mathematics. The keyword 3.78 is the number being divided by 0.9.
The division question posed: 3.78 divided by 0.9, is a simple arithmetic problem. To solve, we will perform the division calculation directly. First, we divide 3.78 (the dividend) by 0.9 (the divisor). This yields a quotient of approximately 4.2. Thus, 3.78 divided by 0.9 equals 4.2 when rounded to the nearest tenth. This division problem would be typically encountered in arithmetic, a branch of mathematics that deals with numbers and numerical computation.
