Each page of a book measures 12 inches by 8 inches. The cover extends beyond the shorter side one half inch in both directions.
sweet-ann [11.9K]
Based on the given condition above for the dimensions of the cover, the length is 12 inches and the new width is 9 inches. Perimeter is twice the sum of the dimensions, 
 
                                      P = 2 x (L + W)

Substituting the known dimensions,
 
                                      P = 2 x (12 in + 9 in) = 42 in

Therefore, the perimeter of the cover is <em>42 inches</em>.

3) What is the measurement of each side if the perimeter is 78?<br> (3x - 4) cm<br> (2x + 3) cm
Goshia [24]
There are 4 sides so add 4 sides
3x-4+3x-4+2x+3+2x+3=78

Combine like terms
10x-2=78

Add 2 to each side of the equation
10x=80

Divide by 10
X=8

Enter x into equation
3(8)-4=20
2(8)+3=19

Multiply by 2
20 x 2= 40
19 x 2 = 38
40 +38 =78

Side 1- 20
Side 2- 19
Side 3- 20
Side 4- 19
