area of rectangle = base x height = 9 x 10 = 90 square cms
Perimeter is the length of a closed line around an area. A rectangle is an area. If each long side of the rectangle is 12 cm and each end of the rectangle is 9 cm, the total length is 14+14+9+9 or 46 cm.
if one length is 9cm, the other length must be 6cm to make an area of 54cm. hence the perimeter is 9+9+6+6 = 30cm
100 is the scale factor
A = LW A = (9 cm)(4 cm) = 36 cm^2
It is: 4*9 = 36 square cm
4 cm * 9 cm = 36 square cm.
Of course. A rectangle that is 5 by 5 (yes, that's a square, but a square is a rectangle) has a perimeter of 5 + 5 + 5 + 5 = 20 and an area of 5 x 5 = 25. A rectangle that is 9 by 1 also has a perimeter of 20 (= 9 + 1 + 9 + 1) but an area of 9 (= 9 x 1).
