A rectangle has a perimeter of 56 cm. The length of the rectangle is 4 cm more than its width. Find the number of sq cm in the area of the rectangle
Let the width of the rectangle be x cm.
Therefore, the length of the rectangle would be (x+4) cm.
The perimeter of a rectangle is given by the formula: 2(length + width)
So, in this case, the perimeter is 2(x+4 + x) = 56 cm
Simplifying, we get 2(2x + 4) = 56
4x + 8 = 56
4x = 48
x = 12
Therefore, the width of the rectangle is 12 cm and the length is 16 cm.
The area of a rectangle is given by the formula: length x width
So, the area of this rectangle would be 12 x 16 = 192 sq cm.
So, the area of the rectangle is 192 sq cm.
