The width of a rectangle is 8 inches and the perimeter is 26 inches. What is the length of the rectangle?
fredd [130]

Length of the rectangle is 5 inches

Step-by-step explanation:

  • Step 1: Perimeter of the rectangle = 26 in and width = 8 in. Find the length.

Perimeter of the rectangle = 2(length + width)

26 = 2(length + 8)

13 = length + 8

length = 13 - 8

Length = 5 in

You like the size of your MP3 player. The width is 4 centimeters. The length is 7 centimeters. The height measures 1 centimeter.
Basile [38]

Answer:

78mm^2

Step-by-step explanation:

based on the information given, we can tell that the shape of the MP3 player is a rectangle. The formula for the surface area of a rectangle is SA=2WL+2LH+2HW

SA = Surface Area

W = Width

L = Length

H = Height

SA = 2(4)(7) + 2(7)(1) + 2(1)(4)

= 2(28) + 2(7) + 2(4)

= 56 + 14 + 8

= 78
