Question

the ratio of length and breadth of a rectangular plot is 3 :2 and its area is 1200 square metres then find its perimeter​

Answer 1

Given

• A word problem
• Based on mensuration

To Find

• Perimeter of the rectangle

Solution

Let the length and breadth of rectangle be X

According to the question

• Now Ratios of the length and breadth be 3x and 2x

___________________________

Area of Rectangle = Length × Breadth

=>1200m²=3x × 2x

=>6x²=1200

=>x² = 200

=>X =√200

=>X=10√2

Length = 30√2

Breadth=20√2

___________________________

Perimeter of rectangle = 2(L+B)

= 2(50√2)

=100√2

Hence perimeter is 100√2
