Question

The length of rectangle is 20 m more than its width. If the perimeter is 84m, find the length of rectangle
​

Answer 1

Answer:Breadth (b) = 15 cm

Breadth (b) = 15 cmLength (l) = 35 cm

Explanation:

Let breadth of a rectangle = bcm

length (l) = 20 cm more than its breadth

= (b+20)cm

Perimeter of the rectangle (P) = 100 cm [given]

=> 2(length+breadth) = 100cm

=> 2(b+20+b)=100 cm

Therefore,

Dimensions of the rectangle:

Breadth (b) = 15 cm

Length (l) = b+20

= 15+20

= 35 cm
