Length of a rectangle is 5 cm longer than the width. Four squares are constructed outside the rectangle such that each of the sq

Arte-miy333 [17]

Answer:

The perimeter of rectangle is $18\ cm$

Step-by-step explanation:

Let

x------> the length of rectangle

y----> the width of rectangle

we know that

The area of the constructed figure is equal to

$A=xy+2x^{2} +2y^{2}\\A=120\ cm^{2}$

$120=xy+2x^{2} +2y^{2}$ -----> equation A

$x=y+5$ -----> equation B

substitute equation B in equation A

$120=y(y+5)+2(y+5)^{2} +2y^{2}\\120=y^{2}+5y+2(y^{2}+10y+25)+2y^{2}\\120=y^{2}+5y+2y^{2}+20y+50+2y^{2}\\5y^{2}+25y+50-120=0\\5y^{2}+25y-70=0$

using a graphing calculator to resolve the quadratic equation

the solution is

$y=2\ cm$

Find the value of x

$x=2+5=7\ cm$

Find the perimeter of rectangle

The perimeter of rectangle is equal to

$P=2(x+y)\\P=2(7+2)=18\ cm$

PLZ HELP!!!!!!!!!!!!!!!!

elena-14-01-66 [18.8K]

Answer:

$A=77.04\ in^2$

Step-by-step explanation:

we know that

The area of the shaded sections is equal to the area of the circle minus the area of the triangle

$A=\pi r^{2} -\frac{1}{2}(b)(h)$

where

$r=12/2=6\ in$ ----> the radius is half the diameter

$b=12\ in\\h=6\ in$

substitute

$A=(3.14)6^{2} -\frac{1}{2}(12)(6)$

$A=77.04\ in^2$
