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.
7/7 - 4/7 = 3/7
This is the relationship between the quantities
Count how many plots are greater than 4, which in this case, is 8 children.
The answer: Time= Distance divide Speed.
Speed= 675,000 divide 900= 750 minutes. Convert that to hours and that leaves you with 12 hours and a half. If these questions are bothering you, just revise them- they’re speed distance time equations and i’d be blessed if they come up in my maths exam tomorrow.
