Question

28. The breadth of a rectangular garden is 3 m less than the length of
the garden. There is an isosceles triangular garden whose base is
same as the breadth of a rectangular garden and its altitude is 12
m. If the area of the rectangular garden is 4 m? more than the
area of the triangular garden, then find the length and breadth of
the rectangular garden.

​

Answer 1

Answer:

Let Breadth be x

So length =(x+3)

Area=x(x+3)m square=(x square+3x) m square

Base of the isosceles triangle =1\2×x×12 =6xm square

According to our requirements ;

x ^+3x=6x+4

x^-3x-4=0

Using quadratic formula

x=3+or -√25\2

=3+or-5\2

x=4or -1
