The length and breadth of a rectangle are in the ratio 5 : 3. If the length is 8 m more than the breadth, what is the area of the rectangle?
Answer & explanation
Correct answer: option 1
The ratio of length and breadth = 5 : 3.
We know that,
Area of rectangle = length × breadth
= length of rectangle = 5a, breadth of rectangle = 3a
= 5a – 3a = 8
= 2a = 8
x = 4
length of rectangle = 5a = 5 × 4 = 20 m
breadth of rectangle = 3a = 3 × 4 = 12 m
Then, area of rectangle = length × breadth
= 20 × 12 = 240 m2
