Answer:
A
Step-by-step explanation:
a^2 + 144^2 = 145^2
a^2 + 20736 = 21025
a^2 = 289
a = sqrt(289)
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.
Answer:
x=22
Step-by-step explanation:
4x+2+x+3x+2=180
collect like terms
4x+x+3x=180-(2+2)
8x=180-4
8x=176
make x the subject of the formula
x=176/8
x=22
Answer:
5/4
Step-by-step explanation:
You just need to multiply 1/2 by 2 to give you a common denominator:
