Question

The length of a rectangle is 5cm more than its breadth.If the perimeter of the rectangle is 38cm,find its area

Answer 1

$84 cm {}^{2}$

Answer 2

Answer:

84 cm²

Step-by-step explanation:

Let the breadth of the rectangle be x cm.

Then,the length = (x+5) cm

Given:. Perimeter = 38cm

2(length+breadth)= 38cm

2(x+5+x)= 38

4x + 10 = 38

4x= 38-10= 28

$x = \frac{28}{4} = 7$

Thus, breadth=7cm and length = (7+5)cm =12 cm

Area of the rectangle = length × breadth = 12cm×7cm =84 cm²

✅ HENCE THE AREA OF THE RECTANGLE IS 84cm².
