Suppose the Length is L centimetres and the Width W is W centimetres.
Then the area = 72 cm2 implies that L*W = 72 so that W = 72/L cm
Also, perimetre = 34 metres = 3400 centimetres.
So 2(L + W) = 3400 or L + W = 1700
Substituting for W, L +72/L = 1700
Multiply through by L : L2 + 72 = 1700L
or, L2 - 1700L + 72 = 0
Using the quadratic formula to solve this equation gives L = 1699.958 cm and
W = 0.042 cm (to 3 dp).
The other root simply swaps the values of L and W.
Perimeter of a rectangle = twice (length + width), in this case 22 m.
The perimeter is 42 metres.
24 meters
12 meters
You can't.There is a cheap way to do it, though. Say that two sides are 5 meters and that the other two sides are 250 centimeters. (2.5 meters is 250 centimeters)
The perimeter of a rectangle is 42. Meters. The length of the rectangle is threemeter less than twice the width.Mar
Perimeter of rectangle = 2 x (length + width) = 2 x (1.6 + 0.8) = 2 x 2.4 = 4.8 meters
24000 sq.cm.

Perimeter of a rectangle = twice (length + width), in this case 22 m.
11.6 meters = 1,160 centimeters
The perimeter is 42 metres.

The perimeter of a rectangle is given by:P = 2l + 2w, where P is the perimeter of the rectangle, l is the length of the rectangle, and w is the width of the rectangle.P = 2(15) + 2(10) = 50 meters.
