Question

length of rectangle 3 times
its breadth. what are its
length and breadth if itarea is
432 m2​

Answer 1

Answer:

Given,

length of rectangle :- 3 times of breadth

Area of rectangle :- 432m2

• Area of rectangle= 432m2
• 2×(l+b) = 432m2
• 2×(3×b) = 432m2
• 432m2÷ 2 = 216 ( 3 + b)
• 216÷3 =b
• 32 = b
• now we find length
• lenght = 3 times of breadth
• 3x32
• 96

Answer 2

Answer:

Let the length be x m. and breadth be 3x m.

perimeter= 432 m^2

A.T.O.

( x+3x ) = 432

4x =432

x = 432/4

x = 108

The length are 108 m.

And breadth are 3×108 = 324 m.
