The length of a rectangle is 6cm longer than its width. If the perimeter of the rectangle is,76cm find its length and width.

1 answer:

3 0

Say the width is x, the length would be x+6
2x+2(x-6)=76
2x+2x-12=76
4x=88
x=22
So the width is 22 and the perimeter is 28

Answer:

The total area of the two rooms is 188.25 square feet

Step-by-step explanation:

Given:

Area of the kitchen = 132 square feet.

Dimension of the Laundry room = 8 1/3 feet by 6 3/4 feet.

To Find:

The total area of the two rooms = ?

Solution:

Area of the two rooms = Area of the kitchen + Area of the laundry room

Area of the two rooms = 132 + Area of the laundry room

Area of the laundry room = $(8 \frac{1}{3}) \times (6 \frac{3}{4})$

Area of the laundry room = $\frac{25}{3} \times \frac{27}{4}$

Area of the laundry = $\frac{675}{12}$

Area of the two rooms = $132 + \frac{675}{12}$

Area of the two rooms = 132 + 56.25

Area of the two rooms = 188.25 square feet

What is the slope of (-18,-20),(-18, -15)

Rzqust [24]

Answer:

Undefined.

Step-by-step explanation:

$m = \frac{rise}{run}$

$m = \frac{ - 15 - ( - 20)}{ - 18 - ( - 18)} \\ m = \frac{ - 15 + 20}{ - 18 + 18} \\ m = \frac{5}{0}$

The denominator is 0. Therefore, the slope is undefined.
