Question

Write the following information in marhematical form
The length of a rectangle is twice its breath and its perimeter is 52

Answer 1

breadth =x

length = 2x

perimeter = 2(l+b)

so

mathematical form

2(x + 2x) = 52

solution is

2(x+2x) = 52

2×3x = 52

6x = 52

x = 52/6=26/3

x = 8.66....(breadth)

length = 2x

2× 8.66....

=17.32

hope it helps you.
