Question

maths formulas class 7th

Answer 1

area of rectangle= length×breadth
are of square=side× side
perimeter of rectangle=2(l+b)
perimeter of square=4×side

Answer 2

Maths formulas which I know of class seventh are -:
1) to calculate the SI = P*R*T/ 100
2) to take out the perimeter of a square = 4*S
3) to take out the perimeter of a rectangle = 2(L+B)
4) to take out the perimeter of a triangle = s+s+s
5) area of a square = S*S
6) area of a rectangle = L*B
7) Area of a triangle = 1/2*H*B


L= length
B= breadth
S= side
SI = simple interest
P= principle
R= rate
T= time
H = height
B= base
