One rectangle that has a perimeter of 30 has a length of 5 and a width of 10.

Perimeter of Rectangle = 2(length + width) =2(45+30) =150 cm

The perimeter of a rectangle is not sufficient to determine its length.

The perimeter of a rectangle is 2 x (length(L) + width). 150 = 2(L + 30) = 2L + 60 2L = 150 - 60 = 90 L = 45

multiple the length by 2 then subtract that from the perimeter. then divide that by two. for example length=10 perimeter=30 ... 30-2(10)= 30-20=10 10/2=5 width=5

the answer to number 20 is B...12

You don't have enough information to find the exact length of the width, but the width has to be less then 7.5 if it smaller then the length.

Perimeter of rectangle = 2 *(l+b) =2 *(45+30)= 2 * 75 =150 cm

(45 + 30) × 2 = 150 centimetres

The perimeter of a rectangle is twice the length plus twice the width.20' x 2 = 40'100' - 40' = 60'60' / 2 = 30'
