Question

Q.6 The area of a rectangle is 448 sq.m. If the length is more than the breadth by 12%, find the breadth
A. 14 m
B. 16 m
C. 18 m
D, 20 m
​

Answer 1

Answer:

Step-by-step explanation:

Let breadth be x,

Area of rectangle = 448m²

Length = 1.12x ( 112% of x )

Now we write the formula for area of rectangle,

⇒ Area of rectangle = L × B

⇒ 448 = 1.12x × x ( input values )

⇒ 448 ÷ 1.12 = x²

⇒ 400 = x²

⇒ √400 = x

⇒ x = 20m

∴ The answer is D, 20m.
