Problema Solution
THE LENGTH OF A RECTANGLE IS DOUBLE ITS BREATH .OF THE PERIMETER OFTHE RECTANGLE IS 30CM ,FIND THE AREA OFTHE RECTANGLE
Answer provided by our tutors
let 'w' represent the width (breath) of the rectangle in cm, then '2w' represents it length in cm
perimeter = 2(length + width)
30 = 2(w + 2w)
15 = 3w
w = 5
2*5 = 10
the width is 5 cm, the length is 10 cm
area = length * width
area = 5 * 10 = 50
the area of the rectangle is 50 cm^2
