Step-by-step explanation:
List the coefficients and constant for an equation in one row of the matrix. The variables should be in the same order. Any missing terms are replaced by zero.
The answers to the three shapes are:
Figure 7; perimeter = 16.2mm, area = 12.64 square mm
Figure 8; perimeter = 15.2inches, area = 9.61 square inches
Figure 9; perimeter = 21.47yards, area = 16.81 square yards
<h3>What is the perimeter of a shape?</h3>Perimeter is the outside boundary of a plane shape.
Analysis:
for figure 7, perimeter = s + s + s = 3s = 3(5.4) = 16.2mm
Height of triangle = = 4.68
Area of triangle = 1/2 base x height = 1/2 x 5.4 x 4.68 = 12.64
For figure 8, perimeter = b + b + a = 5.9 + 5.9 + 3.4 = 15.2 inches
Height of triangle = = 5.65inches
Area of triangle = 1/2 base x height = 1/2 x 3.4 x 5.65 = 9.61
For figure 9, perimeter = b + a + c = 8.2 + 4.1 + 9.17 = 21.47yards
Area of triangle = 1/2 x base x height = 1/2 x 8.2 x 4.1 = 16.81
In conclusion, the perimeter and area of the given shapes are:
Figure 7; perimeter = 16.2mm, area = 12.64 square mm
Figure 8; perimeter = 15.2inches, area = 9.61 square inches
Figure 9; perimeter = 21.47yards, area = 16.81 square yards
