Question

the length of rectangle is greater than its width by 4 cm if the perimeter is 80 cm find the sides of the rectangle

Answer 1

Hey user

Here is your answer :-

Let the width of the rectangle be " x cm " so the length will be x + 4 cm

We know that

Perimeter of the rectangle = 2 ( Lenght + breadth )

80 = 2 ( x + 4 + x )

》80 = 2 ( 2x + 4 )

》80 = 4x + 8

》4x = 72

》x = 72/4

》x = 18

So the breadth of the rectangle is 18 cm and Lenght is 22 cm

Thank you .
