Answer: 20
Explanation: triangle=10 , circle= 5 , square= 4 , half square = 2....... 5 x 2 = 10 plus 10 = 20:)
Formula for perimeter of a square: P = 4a
Formula for area of a square: A = a²
a is given as:
19
Plug this value for a into the above formulas to solve for perimeter and area.
P = 4a
P = 4(19)
P = 76
-----------------------------------------------------------------------------------------------------------------
A = a²
A = 19²
A = 361
Answer:
P = 76 units; A = 361 units².
7.3 km/y
at least if i did this correctly but that's always a stretch.
because it takes 50 days to complete a km
so 365/50 = 7.3
10.6 = 10.6 / 1
Numerator = 10.6 × 10 = 106
Denominator = 1 × 10 = 10
Numerator / Denominator = 106 / 10
The simplified fraction:
= 106/10
= 53/5
= 10 3/5
The answer to the question is C
