As a) The area of a rectangle is 15 cm. If its length is 5 cm, find
breadth (Hint length breadth = Area of rectangle)
b) The area of a rectangle is 28 cm? If its breadth is 4 cm, find its ler
c) If the perimeter of a square is 24 cm, find the length of its
d) The perimeter of a rectangle is 14 cm. If its length is 4 cm, fi
breadth. (Hint: 2(length + breadth) = perimeter of rectangle)
Algebraic !
(Hint: 4 x length of a side = perimeter of square)
e) The volume of the adjoining cuboid is
42 cm. If its length and breadth are 7​

Explanation:

area of rectangle=l×b15=5×bb=3cm

2.area of rectangle=l×b

28=l×4l=7cm

3. perimeter of square=4×L

24=4×LL=6cm

4. perimeter of rectangle=2(L+b)

14=2(4+b)14=8+2b2b=6b=3cm

hope it helps.

The answer is 4 i don't know if its right let me see.

Van der waals forces are temporary electromagnetic forces established between uncharged atoms. some neutral molecules, when close together, can become temporarily “charged,” as electrons move around the atom. water is a polar molecule, the side of the molecule that the hydrogens bond to being more positive, and the opposite side bound to the lone pairs of electrons being more negative. this means that it participates in dipole-dipole interaction (non-polar exhibits dispersion forces), and it has the capacity for hydrogen bonding.
