Question

The area of a square field is 784 sq m. Find the length of its side

Answer 1

Area  is 784 sq m Let its side = s Area = s×s 784 = s² √784 = s 28 = s Therefore the length of its side is 28m

Answer 2

Concept

The area of a square is

area = side * side

and since the sides are equal in a square, it can also be written as

area = side^2

Given

a square field with an area = 784 sq m.

Find

we need to find the length of the given square field.

Solution

We have

area of the square field = 784 sq m

we know the formula for a square's area is

area = side^2

let side of the field be s

thus,

s^2 = 784

s = sqrt(784)

the square root of 784 is 28

⇒ s = 28

Thus, the length of the square field is equal to 28 meters.
