in short, 25% is just 1/4 of anything, we know she's sold 25% which is $600, so her daily goal must be 1/4 + 1/4 + 1/4 + 1/4, or namely 600 + 600 + 600 + 600 = 2400.
Answer:
21 cm by 21 cm
Step-by-step explanation:
The formula for the area of a square is A = x^2, where x is the length of any one side of the square. Here,
441 cm² = x²
This actually has two roots: {√441, -√441), but since x must be positive here, to be a dimension of the square, we choose +√441, or +21.
The dimensions of the square are 21 cm by 21 cm.
Answer:
63 m^2
Step-by-step explanation:
The figure appears to be a parallelogram.
area of parallelogram = base * height
Use the 14-m side as the base. Then the height is the perpendicular distance between the two opposite 14-m sides, so the height is 4.5 m.
area = base * height
area = 14 m * 4.5 m
area = 63 m^2
P.S. The choices are given in square meters (m^2), which is a unit of area, not in meter times square root of 2 "m sqrt(2)."
