Answer: In mathematics, an area model is a rectangular diagram or model used for multiplication and division problems, in which the factors or the quotient and divisor define the length and width of the rectangle. Then we add to get the area of the whole, which is the product or quotient.
Step-by-step explanation:
Answer: s/12 = v
Step-by-step explanation:
Answer:
At first we should know that:
<u>The properties of the square are:</u>
- It has four equal sides.
- All angles are right angles or equal to 90º.
- The sum of its all angles is 360º
- It has two pairs of perpendicular lines.
- It has two pairs of parallel lines.
<u>The properties of Rhombus</u>
- It has equal four sides.
- The opposite sides are of the same length.
- It has two acute angles and two obtuse angles.
- The sum of its all angles is 360º
- It has zero pairs of perpendicular lines.
- It has two pairs of parallel lines.
So, Wade is incorrect because the quadrilateral may be <u>Rhombus</u>
And the quadrilateral to be a square, she needs to show that It has two pairs of perpendicular lines.
Answer:
(x^2 + 2x - 21) sq units
Step-by-step explanation:
Area of the shaded region = Area of the larger rectangle - Area of smaller rectangle
Area of the larger region = x(x+2)
Area of the larger region =x^2 + 2x
Area of the smaller rectangle = 3 * 7
Area of the smaller rectangle = 21 sq. units
Area of the shaded region = x^2 + 2x - 21
Hence the required expression is (x^2 + 2x - 21) sq units
