Question

The areas of a rectangle and a square are equal. If the length of the rectangle is 16 cm and
breadth is 9 cm, find the side of the square.​

Answer 1

Answer:

Area of rectangle : length × breadth = 16 × 9 = 144cm

Area of square = Area of rectangle

4a = 144

a = 144/4

= 36

Hence the side of square is 36 cm

Answer 2

Given - area of rectangle = area of square

length of rectangle = 16 cm

breath of rectangle = 9 cm

so.

Area of rectangle= l×b

Area of rectangle =16×9 cm²

Area of rectangle= 144 cm²

now.

Area of square = 144 cm²

side of square = √area

side of square =√144 cm²

side of square = √12×12 cm×cm

side of square = 12cm
