The measurements of a field are as shown: (FIGURE) If the total area of the field is 27500 sq.m,then the value of x is equal to (a) 25m (b) 30m(c)50m(d)75m

The perimeter of a square whose area is 225\ m^2 is: (a) 15m (b) 60m (c) 225m (d) 30m

Factorise the following expressions. 25m^2 + 30m + 9

A parallelogram has sides 30m and 14m and one of its diagonals is 40m long.Then,its area is 168backslash m^(2) (b) 336backslash m^(2) (c) 372m^(2) (d) 480backslash m^(2)

The factors of 25m^2+30m+9 will be :
