Answer:
278.25 cm2
Step-by-step explanation:
If the width of the rectangle is x (cm), as the length is 8cm longer, so that the length of the rectangle is: x + 8 (cm).
In the attached image, we can see the length of each side. Total length of the sides are 90 cm.
=> (x + x + 8) + x + 8 + (x+8) + (x + x + 8) + x + 8 + (x +8) = 90
=> 8x + 48 = 90
=> 8x = 90 - 48 = 42
=> x =42/8 = 5.25 (cm)
=> The width of the rectangle is 5.25cm
=> The length of the rectangle is: 5.25 + 8 = 13.25 cm
=> The area of one rectangle is: Length x Width = 5.25 x 13.25 = 69.5625 cm2
As the 8-sided shape is made from 4 rectangles, so that:
Area of 8 sided shape = 4 x Area of the rectangle = 4 x 69.5625 = 278.25 cm2
8 and -8 cuz theyre both 8 in absolute form

Answer:
x= $878.85
Step-by-step explanation:
1349.99=1350
1350=100% you cross multiply and then divide by 100 you get x = 540
x =40%
504 is how much can be off the original price, 1350-504=810
You would pay 810 dollars if the coupon was 40% off. Now we gotta find how much is the tax rate.
810=100% do the cross multiply and then divide by a 100, you get x=68.85
x =8.5
Then you have to add your tax rate to the price that you are paying, 810+68.85=$878.85.
Hope this helps you!
