Question

the length of a rectangle is 6 cm more than its breadth if the perimeters of a rectangle is 60 cm find its length and breadth also find its areas

Answer 1

take breath as x

1. take length as x+6
2. now,perimeter is 60cm
3. perimeter=2(l+b)
4. 60=2(x+6+x)
5. 60=2(2x+6)
6. 60=4x+12
7. 60-12=4x
8. 48=4x
9. x=48÷4
10. x=12
11. now we got the breath is 12cm
12. length is 6cm more than the breath
13. so l=x+6
14. l=12+6
15. l=18
16. we got length is 18cm
17. now area
18. area=l×w
19. area=18×12cm²
20. area=216cm²
