Question

a rectangle has the longer side three times the smaller side if the area of the rectangle is 48 CM square what is the length of the longer side​

Answer 1

Answer:

longer side= 12cm

shorter side 4cm

Answer 2

Let length of smaller side is x.

Then ,

Length of longer side is 3x.

Area of rectangle = 48 cm²

L×B = 48

3x×x = 48

3x² = 48

x² = 16

x = √16 = 4 cm

Now, longer side of rectangle = 3x => 3×4 => 12 cm.
