Question

Find the approximate side length of the square with each area.

Give your answer to the nearest millimetre.
a) A = 50 cm
b) A = 125 cm

Answer 1

a) √50 = 5√2 = about 7.1 cm

= about 71 mm

b) √125 = 5√5 = about 11.2 cm

= about 112 mm

Answer 2

To find the approximate side length of a square with a given area, take the square root of the area and round to the nearest millimeter.

Step-by-step explanation:

To find the approximate side length of a square with a given area, we can take the square root of the area. Let's solve for each case:

a) A = 50 cm

The square root of 50 is approximately 7.071 cm. Rounded to the nearest millimeter, the approximate side length is 7 cm.

b) A = 125 cm

The square root of 125 is approximately 11.180 cm. Rounded to the nearest millimeter, the approximate side length is 11 cm.
