Answer:
Area of Rectangle = 28 cm²
Step-by-step explanation:
Given - A rectangle has coordinates (2, 6) (9, 6) (9, 10) and (2, 10) on a grid with 1 cm squares.
To find - What is the area of the shaded rectangle?
Solution -
The graph of the rectangle is as follows :
From the diagram, e can see that
Length of Rectangle = 7 units (cm)
Breadth of Rectangle = 4 units (cm)
We know that,
Area of Rectangle = Length × Breadth
= 7 × 4
= 28 cm²
⇒Area of Rectangle = 28 cm²
Answer:-21
Step-by-step explanation:
3•(-7)
3 x -7=-21
Answer:
2x + 6
Step-by-step explanation:
The area of a square is the square of the side length:
A = s²
We know that the area of the square is 4x² + 24x + 36.
4 is 2², and 36 is 6². 24 is double 2 times 6.
Therefore, this is a perfect square trinomial:
A = 4x² + 24x + 36
A = (2x + 6)²
Therefore:
s = 2x + 6
