Answer:
a. 823.23
Step-by-step explanation:
used a motgage calculator
1 foot is 12 inches
Convert everything to inches:
28 x 12 = 336 in.
39 x 12 = 468 in.
Add all the inches together:
336 + 468 + 7 + 8 = 819 in.
The answer is 819 inches.
100 x 37= 3700

Explanation:
_____________________________________________
2 / 3 = (4.5) / x ; Solve for "x" ;
2x = (3)(4.5) ;
Divide each side of the equation by "2" ; to isolate "x" on one side of the equation; and to solve for "x" ;
_________________________________________________
2x / 2 = [3*(4.5)] / 2 ;
to get: x = (13.5)/2 = 6.75 ft. This is already rounded to the
nearest hundredth.

a. Ratio of blue: green
Length blue: length green
3:6 or 1:2
Width blue :width green
2:4 or 1:2
Perimeter blue: perimeter green
2+2+3+3=10: 4+4+6+6= 20 or 1 :2
Area blue: Area green
2•3=6 : 4•6= 24 or 1:4
b. The lenght, with and perimeter of the big green rectangle are double the size of the small blue rectangle.
The area of the big green rectangle is 4 times greater than the area of the small blue rectangle. So if the lenghts of a rectangle are doubled the perimeter is doubled and the area is 4 times biger than the area of the doubeled rectangle.
