Alona [7]

Answer:

$P= 2*Lenght + 2*Width$

Since the perimeter is 56 inches we can solve for the lenght with this equation:

$56 in = 2*12in + 2*Length$

And solving for the length we got:

$Length = \frac{56in -24 in}{2} 16 in$

So then the lenght = 16 inhes and the width of 12 inches

Step-by-step explanation:

For a rectangle of width 12 inches and lenght y inches we know that the perimeter is given by:

$P= 2*Lenght + 2*Width$

Since the perimeter is 56 inches we can solve for the lenght with this equation:

$56 in = 2*12in + 2*Length$

And solving for the length we got:

$Length = \frac{56in -24 in}{2} 16 in$

So then the lenght = 16 inhes and the width of 12 inches

Answer:

Area of parallelogram is 150 square ft

Step-by-step explanation:

Given the parallelogram in the figure whose height is 10 ft and base length is 15 ft.

Area of parallelogram is $base \times height$

= $15\times 10ft^2$

= 150 square ft

now we have to decompose this parallelogram into rectangles and triangles and then to determine the shape.

The given parallelogram KLMN can be decomposed into 2 triangles and one rectangle.

2 right angled triangles KPL and NOM by construction

$KL^{2}=KP^{2}+PL^{2}=10^{2}+2^{2} =100+4=104$

⇒ $KL=\sqrt104=10.2 ft=MN$ (∵ KLMN is a parallelogram)

Hence, dimension of triangles are 10 ft, 2 ft and 10.2 ft

Now rectangle KPON with dimension 15 ft and 10 ft because KP and NO are perpendiculars on LM.
