Area of rectangle = 24/54 square miles
length(L) = 5/9 miles
width (W)= ?
area = L * W
25/54 = 5/9 * W
W = (25/54) / (5/9) = (25 * 9) / (54 * 5)
W = 5/6 miles
Answer:
Angle ABC =40º.
Step-by-step explanation:
We know that angle ABD = 70º. We also know that angle CBD= 30º . Therefore angle ABD - angle CBD will give us the measurement of angle ABC. 70º - 30º= 40º.
Answer:
A. 220
Step-by-step explanation:
To find the total surface area of a square pyramid, you have to find the area of the base and all of the sides and add them together.
To find the area of the base:
Since the base is a square, all we have to do is multiply the length by itself.
10 * 10 = 100
The base is 100 square centimeters
To find the area of the sides:
Since the sides are triangles, we have to multiply the length times the height and divide it by 2.
10 * 6 = 60
60/2 = 30
The area of one side is 30 square centimeters
To find the total surface area:
Add the area of all 4 sides and the area of the base together to find the total surface area.
4(30) + 100 = surface area
120 + 100
220 = surface area
The surface area is A. 220 square centimeters.
