The perimeter is adding all four sides together.
In a rectangle the two opposite sides are identical, so there are two sides 2 ft long and 2 sides 3.4 ft long.
Perimeter = 2 + 2 +3.4 + 3.4 = 10.8 feet.

To find the area of this entire shape, we must divide it into two rectangles.
The first rectangle is on the bottom of the shape, with a length of 8 cm and a width of 3 cm.
The second rectangle is on the top of the shape. The length is (8-5) cm and the height is (7-3) cm.
To find the area of the total shape, we must add the areas of the two rectangles. To find the area of the rectangle, we use the formula, A = l * w.
8 * 3 = 24 cm^2
3 * 4 = 12 cm^2
24 sq cm + 12 sq cm = 36 square centimeters.
Therefore, the area is 36 square centimeters. Hope this helps! :)
Given:
A number line from -10 to 10 with 20 tick marks.
Point D is 1 tick mark to the left of 5.
To find:
The integer value that represents point D.
Solution:
A number line from -10 to 10 with 20 tick marks. It means, each mark represents the integer values from -10 to 10.
We know that, as we move towards left on a number line the value decreases and as we move towards right the value increases.
Point D is 1 tick mark to the left of 5. It means, point D represents the integer value which is 1 less than 5.
Therefore, point D represents the integer 4.
Answer:
25°
Step-by-step explanation:
the sum of angles in a Δ = 180°
the largest angle = 100°
the second largest angle = x + 30
the third angle = x
100 + (x +30) + x = 180
100 + x + 30 + x = 180
130 + 2x = 180
2x = 180 - 130
2x = 50
x = 50/2 = 25°
the largest angle = 100°
the second largest angle = x + 30 = 25 + 30 = 55°
the third angle = x = 25°
100° + 55° + 25° = 180°
