yeah the answer is 1000 trees. bro because see 4km 800m = 4800 by multiply we had converted it to metres to solve the sum. then step2= we will divide it to 9.6 because it has said to have intervals and to find the intervals we need to divide as we dont know how is the length is by after the interval and after the answer will be 500 step3= then the trees are planted both sides of the roads so multiply with or by 2 and the answer is 1000 trees.

(H)2=(P)2+(B) 2

Ans 2:

Class : Class 8
Hypotenuse=(side1)*2+(side2)*2

Ans 3:

Class : Class 7
The pythagoras' theorem states that the square of the hypotenuse is equal to the sum of the square of the other 2 sides. The equation would be hyp2=S12+S22 note: the 2 is the power of two

Ans 4:

Class : Class 9
(H)2=(P)2+(B)2

Ans 5:

Class : Class 7
Square of hypotenuse=Square of its legs

Ans 6:

Class : Class 7
A2+B2=C2

Ans 7:

Class : Class 8
square of base + square of perpendicular side = square of hypoteneuse

Ans 8:

Class : Class 10
Hypotenuse^2= P^2 + B^2 Here, P=perpendicular height and B=base.

Ans 9:

Class : Class 8
a2+b2=c2

Ans 10:

Class : Class 10
a = 1 side, b = another side, c = hypotenuse (the longest side). The formula is: a2 + b2 = c2 (the two means squared, not multiplied by two). The formula only works in right-angled triangles.

Ans 11:

Class : Class 7
(H)2=(P)2+(B) 2

Ans 12:

Class : Class 8
Asquare+B square = C square (hypotenuse)

Ans 13:

Class : Class 7
(H)2=(P)2+(B) 2

Ans 14:

Class : Class 7
Hypotenuse=base×base+hieght×height Base=hypotenuse×hypotenuse -height ×height Height=base×base - hypotenuse×hypotenuse

Ans 15:

Class : Class 9
square of hypotenuse=sum of square of other 2 legs in a right angled triangle

Ans 16:

Class : Class 8
AB2+BC2=AC2 THIS MEANS THAT IN A TRIANGLE WHEN WE ADD THE SQUARE OF THE BASE AND PARALLEL ANGLE IT WILL ALWAYS BE EQUAL TO THE HYPOTENUSE.

Absolute value means you have to ignore the plus / minus sign. 4*7+3*(2-5) = 4*7+3-3 = 28
