Answer:
i think its 12 :)
Step-by-step explanation:
20 + 48 = 68
180 - 68 = 112
20 + 48 + 112 = 18 (a full triangle!)
Answer: Area = 108 in. or 3/4 ft.
Step-by-step explanation: The formula for the area of a rectangle is l•w (length times width).
To get the area, you need to convert the units of measurement to one or the other (either inches or feet) because you cannot multiply them unless they are the same.
To get the area in inches, you convert 3 ft. to inches which is 36 inches, and then multiply it by 3 inches. You will get that the area = 108 inches.
To get the area in feet, you convert 3 inches to feet which is 1/4 (or 0.25) feet and then multiply it by 3 feet which gives you area = 3/4 ft. (or 0.75 ft.). Hope this helps.
Answer:
A =90 in^2
Step-by-step explanation:
The area of the rhombus is found by
A = 1/2 d1 * d2 where d1 and d2 are the diagonal lengths
d1 = 2*6 =12
d2 = 2 *7.5=15
A = 1/2 (12*15)
A =90 in^2
The slope of the line would be 3
