Question

Find the aerea of the square the length of whose diagonal is 2.8m

Answer 1

Hi...☺

Here is your answer...✌

Let the Side of square be 'a'

GIVEN THAT,

LENGTH OF DIAGONAL = 2.8 m

√2 a = 2.8

a = 2.8/1.4 [ √2 ≈ 1.4 ]

a = 2 m

NOW,

AREA OF SQUARE = a²

= (2)²

= 4 m²

HENCE,

Area of given square is 4 m²
