The length of a rectangle is 5.2cm and its breadth is 3.4cm. What is the area of the rectangle?

Rainbow [258]

Answer:

$\huge{ \boxed{ \sf{17.68 \: {cm}^{2} }}}$

Step-by-step explanation:

$\underline{ \text{Given}} :$

$\longrightarrow \sf{ \: Length \: of \: a \: rectangle \: = \: 5.2 \: cm}$

$\longrightarrow{ \sf{Breadth \: of \: \: rectangle \: = \: 3.4 \: cm}}$

$\underline{ \text{To \: find} } : \sf{Area \: of \: a \: rectangle}$

$\boxed{ \sf{Area \: of \: a \: rectangle \: = \: Length \: \times \: Breadth}}$

$\mapsto{ \sf{Area \: = \: 5.2 \: cm \: \times \: 3.4 \: cm}}$

$\mapsto{ \sf{Area \: = \: 17.68 \: {cm}^{2} }}$

Hope I helped!

Best regards! :D

Kathy is fencing in her yard that has an area of 800 square feet. Her yard is in the shape of a rectangle where the length is 60

anygoal [31]

Answer:

The dimensions of the yard are W=20ft and L=40ft.

Step-by-step explanation:

Let be:

W: width of the yard.

L:length.

Now, we can write the equation of that relates length and width:

$L=5W-60$ (Equation #1)

The area of the yard can be expressed as (using equation #1 into #2):

$Area=W*L=W*(5W-60)$ (Equation #2)

Since the Area of the yard is $800 ft^2$ , then equation #2 turns into:

$800=W*(5W-60)$

Now, we rearrange this equation:

$800=W*(5W-60)//800=5W^2-60W//5W^2-60W-800=0$

We can divide the equation by 5 :

$W^2-12W-160=0$

We need to find the solution for this quadratic. Let's find the factors of 160 that multiplied yields -160 and added yields -12. Let's choose -20 and 8, since $(-20)*8=160$ and $-20+8=-12$ . The equation factorised looks like this:

$(W-20)(W+8)=0$

Therefore the possible solutions are W=20 and W=-8. We discard W=-8 since width must be a positive number. To find the length, we substitute the value of W in equation #1:

$5*20-60=40$

Therefore, the dimensions of the yard are W=20ft and L=40ft.
