The surface area of the provided figure is 1051.2 square ft after calculating the area separately.
<h3>What is the area of the rectangle?</h3>
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
We have given a three-dimensional figure with dimensions.
The surface area = area of seven rectangles + area of two triangle
= 15×9 + 2(15×12) + 2(9×12) + 2(9×15) + 2(1/2)[9(19.8-12)]
= 135 + 360 + 216 + 270 + 70.2
= 1051.2 square ft
Thus, the surface area of the provided figure is 1051.2 square ft after calculating the area separately.

Answer: Reflection across the y axis.
Clockwise rotation
Step-by-step explanation:
A² - ab + 8b + b² - 1
There are 5 terms in the expression.
a² = 1st term
ab = 2nd term
8b = 3rd term
b² = 4th term
1 = 5th term
Each term is separated by a plus (+) sign or a minus (-) sign.
A term is either a number, a variable, or a number and a variable multiplied together.
a², ab, b² are variables.
8b is a number and a variable multiplied together
1 is a number.
Answer: 3.5a+5b=470 and a+b=115
Step-by-step explanation:
Its a bc of the roation it made to a 90 degrees
