Question

what will be the values of x and y if in a rectangle it's length is 5cm , perimeter is 10 cm and breadth is (x-y)cm

Answer 1

Step-by-step explanation:

Given,,,

In rectangle,, length is 5cm.

perimeter of the rectangle is 10cm.

breadth is (x-y) cm.

As we know that ,,

area of the reactangle is,,

2(length + breadth)sq.unit.

So let's find the value of x & y,,

area of the rectangle = 2(l+b) sq.unit.

; 10 = 2(5+x-y)

; 10 = 10 + 2x -2y.

; 10-10 = 2x - 2y.

; 0 = 2x - 2y.

; 2x = 2y.

; x = y.

THIS TELLS US THAT VALUE IF "x" & "y" ARE EQUAL,, BUT NOT SHOW THE EXACT VALUE OF "x" & "y".

HOPE IT WILL BE HELPFUL
