The length of a rectangle is 2x + 6. Its width is 52. Find the value of ac if the perimeter is 138m².
Sergeeva-Olga [200]

Answer:

ac = 18.5

Step-by-step explanation:

perimeter of a rectangle =  2(l+b)

= 138m^2= 2(2x + 6 ) + 52

= 4x + 12 + 52 = 138  

= 4x + 64 = 138

= 4x = 138 - 64

= 4x = 74

= x =  74/4

= x = 18.5
