Given area of square field =0.25 hectare
1 hectare =10,000m =0.25×10,000 =0.25×100 =2500 sq. m
Let side of square be 'a'
Area of square =a 2 a 2 =2500 ⇒a=50m
Diagonal of square = 2 a= 2 ×50=50 2 ​ m.

If 7m = 35, then 7m + 4 = 35 + 4<br> NAME THE PROPERTY
Reptile [31]

The property that is applied in 7m+4=35+4 is addition property of equality

Given :

If \; 7m=35, then \; 7m+4=35+4

From the above equation we can see that 4 is added at the both sides of the equation .

we can add same number at the both sides of the equation to balance the equation . That is called as addition property of equality

Here , 4 is added on both sides of the equality to balance the equation .

So , addition property of equality is applied .

Alina [70]

Answer:

DE = 13.4 cm  (to 1 decimal place)

Step-by-step explanation:

Given: ABCD is a square

BC = AC = 12 cm    (opposite sides of a square are congruent)

E is midpoint of BC   (given)

BE = EC  = 12/2 = 6 cm

CD = AB = 12 cm   (opposite sides of a square are congruent)

angle ECD is a right angle (interior angles of a square are 90 deg.)

Consider right triangle ECD

DE = sqrt(EC^2+CD^2)    ............. pythagorean theorem

= sqrt(6^2+12^2)

= sqrt ( 36+144 )

= sqrt (180)

= 2 sqrt(45)

= 13.416 (to three dec. places)
