Answer:

$\huge\boxed{\sf Area\ of\ the\ circle = 1385.4\ in.\²}$

Step-by-step explanation:

We have to find out the area of the square in order to find how many square inches were cut from the squared cloth.

Diameter = 42 in.

Radius = D / 2 = 42 / 2 = 21 in.

Area of circle = πr²

Where r = 21 in.

Area = (3.14)(21)²

Area = (3.14)(441)

Area of the circle = 1385.4 in.²

$\rule[225]{225}{2}$

Hope this helped!

Can someone please do this i suck at math

Answer:

Width = y + 7x

Step-by-step explanation:

Area of the rectangle = ${y}^{2} + 8xy + 7 {x}^{2}$

Length of the rectangle = $y + x$

Lets factorise ${y}^{2} + 8xy + 7 {x}^{2}$

$= > {y}^{2} + xy + 7xy + {x}^{2}$

$= > y(y + x) + 7x(y + x)$

$= > (y + 7x)(y + x)$

Now ,

Width = $\frac{Area}{Length} = \frac{(y + 7x)(y + x)}{(y + x)} = y + 7x$
