Question

area of rectangle with one side 8 cm is 172 CM square find the length of the other side

Answer 1

let the length be 'x'

area of rectangle= b×l
172=8×x
172÷8=x
21.5=x
x=21.5cm

Answer 2

Given Area of rectangle = 172cm.

We know that Area of rectangle = l * b

                            172 = 8 * b

                              b = 172/8

                                 = 21.5.


The length of another side = 21.5cm.
