Question

The length and breadth of a rectangle is (x-y) units and (3x+y) units. Find the area of the rectangle.

Answer 1

Answer:

Step-by-step explanation:

Area = length * breadth

= (x - y) * (3x + y)

= 3*x^2 - 2*x*y - y^2

Answer 2

Mark as a brainlist dood plz

This is not urAnswer:

But this will help u..........

Step-by-step explanation:

Perimeter of rectangle = 100m

ratio of length is to breadth = 3:2 = 3x : 2x

Perimeter = 2(l+b)

P = 2(3x+2x)

= 6x + 4x = 10x

10x = 100 ; x = 100/10 = 10

l = 3x = 3 × 10 = 30 m

b = 2x = 2 × 10 = 20 m

Area of rectangle = length × breadth ( l×b )

A = 30 × 20 = 600 sq.m
