Question

A square has the same area as a rectangle with sides of length 9cm and 16cm. What is the length of the side of the square

Answer 1

Answer:

area of rectangle = 16 × 9

= 144 cm²

area of rectangle = area of square = 144cm²

since area of square = a²

a² = 144

a = 12 cm

so the length of side of square is = 12 cm

Answer 2

Answer:

12 cm

Step-by-step explanation:

$Area_{rectangle} = 9*16 = 144 cm^2$

$Area_{rectangle} = Area_{square}$

$Area_{square} = a^2$ = 144

a = √144 = 12 cm
