(Q) The length and breadth of a rectangular piece of fabric are in the ratio 7:4. The length of the fabric is 15 m more than that of the breadth. Find the area that this fabric would cover
A) 700 sq.m.
B) 658 sq.m.
C) 720 sq.m.
D) 685 sq.m.
Explanation : Let the common factor be X
∴ Length = 7X and Breadth = 4X
Also, 4X+15m = 7X
∴ X = 5
∴ Area of Rectangular ground = Length x Breadth = 7X x 4X = 35 x 20 = 700 sq.m.
B) 658 sq.m.
C) 720 sq.m.
D) 685 sq.m.
