A small square is entirely contained in a larger square, as shown. The side length of the small square is 3 units and the side length of the larger square is 7 units. What is the number of square units in the area of the black region
Based on the calculations, the area of the black region is equal to 40 sq. units.
How to calculate the area of a square?Mathematically, the area of a square can be calculated by using this formula;
A = x²
Where:
A is the area of a square.x is the side length of a square.By critically observing the diagram (see attachment), we can logically deduce that the black region represents the area within the larger square and partially occupied by the small square. Thus, we would calculate the area of the black region by subtracting the area of the small square from the area of the larger square as follows:
Area of small square = 3²
Area of small square = 9 sq. units.
For the larger square, we have:
Area of small square = 7²
Area of small square = 49 sq. units.
Now, we can calculate the area of the black region:
Area = 49 - 9
Area = 40 sq. units.

In the figure, the coefficient of kinetic friction between the surface and the larger block is 0.20, and the coefficient of kinetic friction between the surface and the smaller block is 0.30. If F
The tension on the connecting string of the two blocks is 6 N.
The following were given from the question;coefficient of friction between the surface and larger block, μ₁ = 0.20
coefficient of kinetic friction between the surface and smaller block, μ₂ = 0.3
horizontal force, F = 10 N
mass of the larger block, m₁ = 2M = 2 kg
mass of the smaller block, m₂ = M = 1 kg
We use the formula below to determine the rate of change of acceleration along the horizontal block
F +μ2Mg - μ1(2M)g = a(M+2M)
10+0.3×1×9.8 - 0.2×2×9.6 = a(1+2)
