FOIL is an ancronym to help you remember to multiply each term. basically it's for people who can't distribute good
anwya
FOIL stands tells you which terms to mulitply, you then add the results up
F=First terms
O=Outer terms
I=Inner terms
L=Last terms
so
(x-2)(x-3)
First: x times x =
Outer: x times -3=-3x
Inner: -2 times x=-2x
Last: -2 times -3=6
now add them all up
answer is the second option
The area of the composite figure from the image attached is 112.5 units²
<h3>What is the area of a composite figure?</h3>The area of a composite figure refers to the sum total of all the areas of the shapes in that composite figure. This can be done by first identifying the shapes in that composite figure, then finding each area, followed by the addition of all the areas to determine the area of the composite figure.
From the given figure; we can break it down into:
- A parallelogram
- A rectangle
- A triangle
The area of a parallelogram = b × h
where;
- b & h refers to the length of the two opposite diagonal lines.
The area of a parallelogram = 9 × 6
The area of a parallelogram = 54 units²
The area of a rectangle = Length × breadth
The area of a rectangle = (9 × 3) units²
The area of a rectangle = 27 units²
The area of the triangle
where;
- Base = b
- Height = h
The area of the triangle
The area of the triangle
The area of the triangle
Therefore, the area of the composite figure is:
= 54 + 27 + 31.5
= 112.5 units²
