Answer: There are 165 boys
Step-by-step explanation:
Let's call b the number of boys and call g the number of girls in the class.
Then we know that:
There are 462 students. This is:
We also know that there are 132 more girls than boys, this means that:
Now we substitute the second equation in the first and solve for b.
The solution is, The area is 280.8 inches² of one triangular section.
Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
here, we have,
given that,
If the base of the panel is 31.2 inches and the height is 18 inches,
we know that,
Area of triangle = base × height ÷ 2
here, we have,
b = 31.2
h= 18
so, we get,
A = 18 × 31.2 ÷ 2
we know,
18 × 31.2 ÷ 2 = 280.8
so, A = 280.8
The area is 280.8 inches².
Hence, The solution is, The area is 280.8 inches² of one triangular section.

Width of the rectangle is 14 ft
Step-by-step explanation:
Perimeter = 2(length + width)
72 = 2 (8 + x + x)
72 = 16 + 4x
4x = 56
x = 56/4 = 14
∴ Width of the rectangle is 14 ft
