Question

The side of a square is 5 1by 4 cm long . Find the perimeter and area of the square.
​

Answer 1

Answer:

The area and perimeter of a square are 27.5625 cm² and 21 cm respectively.

Step-by-step explanation:

The side of a square is of dimension:

$a=5\frac{1}{4}=\frac{21}{4}=5.25\ cm$

Compute the area and perimeter as follows:

$Area=a^{2}=(5.25)^{2}=27.5625\\Perimeter = 4a=4\times 5.25=21$

Thus, the area and perimeter of a square are 27.5625 cm² and 21 cm respectively.

Answer 2

Answer:

51/4 = 12.75 cm

perimeter of square = 4 x side

= 4×12.75 = 51 cm

area of square = side× side

= 12.75 × 12 .75 = 162.5625 cm^2....
