area = width x height = 30 square feet ( not feet)
5 x height = 30
height = 6 feet
perimeter = 2 width + 2 height = 10 + 12 = 22 feet
4 feet
50 cm2
Write two simultaneous equations and solve them. One for the perimeter, one for the area.
One rectangle that has a perimeter of 30 has a length of 5 and a width of 10.
There is no such thing as the area of the perimeter. A perimeter is a length and so has only 1 dimension. As such, its area is 0.

the answer to number 20 is B...12

we know,area of rectangle = l * b perimeter= 45*30=1350 cm ^2
rectangle with 10" length and 2x-4 width 60" area
The rectangle has a length of 12 cm and a width of 3 cm.
The perimeter is 30 feet for this rectangle.
Perimeter of Rectangle = 2(length + width) =2(45+30) =150 cm
