Answer:
Area= L*W= 13*7 = 91ft^2
Step-by-step explanation:
L= 6+W
Perimeter of the rectangle=2(L+W)=40
2(6+W+W)=40
2(6+2W)=40
12+4W=40
4W=40-12
4W=28
W=28/4
W=7ft
L=6+7=13ft
Area=L*W=13*7=91ft^2
Let thw second integer be x
then the first = 2x
and the third integer is = 6+x
their sum = 74
x+2x+6+x = 74
4x +6 = 74
4x = 74-6 =68
x =68÷4
x = 17
then the first integer is 2×17 = 34
the third integer is 17+6 = 23
the integers are 17 , 23 and 34
