Question

If the length of a rectangle is three times the breadth and the area is 507 cm2, then the length and the breadth are _____________ respectively.

Answer 1

Answer:

Length=13

Breadth=39

Step-by-step explanation:

3l=b...….....given

Area of rectangle=l*b

507=l*b

But b=3l

Therefore, 507=l*3l

507=3l^2

163=l^2

13=l

b=3l

b=3*13=39

Answer 2

Step-by-step explanation:

hai this question is quite easy

read this properly

formula for area of rectangle is lenght *breath

lenght =3*breath

lets take lenght as l and breath as b

first of all as per the question we get b*3b=507

(first of all i concentrate on answer after that i will write units and all okay?)

so coming to the steps..

3b^2=507

b=13

hence breath is 13cm and lenght is 39cm

hai thanks for marking me as best answer
