Answer:
- area of rectangle: 48 cm²
- area of triangle: 18 cm²
- shaded area: 30 cm²
Step-by-step explanation:
The area of a rectangle is given by the product of its length and width.
... A = LW
For your rectangle, the overall area is ...
... A = (12 cm)(4 cm) = 48 cm² . . . . rectangle area
___
The area of a triangle is half the product of its base and height. Your triangle is shown with a base of 9 cm, and its height is the height of the rectangle, 4 cm. The triangle area is ...
... A = (1/2)bh
... A = (1/2)(9 cm)(4 cm) = 18 cm² . . . . triangle area
___
The shaded area of the figure is the difference between the rectangle area and the triangle area. (The triangle is fully included in the rectangle, but is not shaded.) That difference is ...
... shaded area = rectangle area - triangle area
... shaded area = 48 cm² - 18 cm² = 30 cm² . . . . shaded area
Answer:
W-2 form
Step-by-step explanation:
It's A) to find the slope.
The resulted equation is in slope-intercept form which gives the slope (-A/B).
Jasmine is reducing the height of the yearbook picture from 5 inches to 2 inches and we are trying to find the percentage of the original height that is the new height.
The original height was 5 inches and the new height is 2 inches.
new/original = 2/5
2÷5 = 0.4
0.4 = 40%
Thus, the new height is 40% of the original height.
