Answer:

Your answer should be 13

Step-by-step explanation:

You were given 25, so you need to work backwards. First, multiply the 25 by 3 to get 75. Then Add 6, and you end with 81. Afterwards, subtract 3 from 81 to get 78, then divide by 6 to get 13.

The perimeter of a rectangle is 32 inches. The length is 1 foot. What is the width of the rectangle in inches? A. 4 inches B. 10
alekssr [168]

Answer:

A. 4 inches

Step-by-step explanation:

Applying,

P = 2(L+W)............. Equation 1

Where P = Perimter of the rectangle, L = Length of the rectangle, W = width of the rectangle.

make W the subject of the equation

W = (P/2)-L............ Equation 2

From the question,

Given: P = 32 inches, L = 1 foot (Convert from Foot to inches), L = 12 inches

Substitute these values into equation 2

W = (32/2)-12

W = 16-12

W = 4 inches.

Hence the right option is A.

The width of the rectangle is 75% of its length. The length is 8 cm. What is the width of the rectangle?
hjlf

Given :

The length of the rectangle, l = 8 cm/

The width of the rectangle, w = 75% of 8 cm

                                                 $= \frac{75}{100} \times 8$

                                                 $=\frac{15}{20} \times 8$

                                                 = 0.75 x 8

                                                 = 6

Therefore, the width of the rectangle is 6 cm.
