The perimeter of a rectangle is 524 m. The length is 42 m greater than the width. what is the length of the rectangle

1 answer:

6 0

Let the width be x

Width = x
Lenght = 42 + x

Perimeter of a rectangle = (2 x width) + (2 x lenght)
524 = (2x) + [2(42 + x)]
524 = 2x + 84 + 2x
440 = 4x
110 = x

Width = 110
Length = 42 + 110 = 152

a circle with radious of 1cm sits inside a 11cm times 12 cm rectangle what is the area of the shaded region

Nitella [24]

Answer: 128.86cm²

Step-by-step explanation:

The circle is inscribed in the rectangle. To find the shaded portion, subtract he area of the circle from the are of the rectangle.

Area of the rectangle = 11 x 12

= 132cm²

Area of the circle with radius of 1cm = πr²

= 3.142 x 1²

= 3.142cm²

Therefore , area of the shaded region = 132cm² - 3.142cm²

= 128.86cm²

Solve for x. 3/4 = x/12 <br> I need work shown to

marta [7]

$\frac{3}{4} = \frac{x}{12}$

To solve for x you have to bring the 12 to the other side

How do we do this?

Well if you think about it this is technically what the equation shows

$\frac{3}{4} = x * \frac{1}{12}$

This means to isolate x you can multiply both sides by 12 and that will cancel $\frac{1}{12}$ from the right side

$\frac{3}{4} * 12 = x * \frac{1}{12} * 12$

$\frac{36}{4} = x * 1\\\frac{36}{4} = x$

$\frac{36}{4}$ can be further simplified to...

^^^This is the answer

Check:

3/4 = 9/12

3/4 = 3/4

Hope this helped!
