Step-by-step explanation:

The length of a rectangle is 1 metre more than its breadth. It area is 3 3/4 square metres. What are its length and breadth?

Solution: Area of the rectangle = 15/4 m^2

L = B+1

B(B+1) = 15/4, or

4B^2+4B-15 = 0

4B^2+10B-6B-15 = 0

2B(B+5) - 3(B+5) = 0

(2B-3)(B+5) = 0

So, B = 3/2 m and L = 5/2 m. Answer.

Answer 2

Answer:

Solution: Area of the rectangle = 15/4 m^2

L = B+1

B(B+1) = 15/4, or

4B^2+4B-15 = 0

4B^2+10B-6B-15 = 0

2B(B+5) - 3(B+5) = 0

(2B-3)(B+5) = 0

So, B = 3/2 m and L = 5/2 m.
