Question

The length of a rectangle is twice the width of it. If the perimeter of the rectangle is 42m. Then the area of the rectangle is _____ .

• A. 98 m²
• B. 224 m²
• C. 63 m²
• D. 108 m²

Answer 1

The correct option is A

98 m²

Let the breadth of rectangle be x

Length = 2x

Perimeter, 2(x + 2x) = 42 m

3x = 21,

On solving, we get x = 7

Breadth = 7 m

Length = 14m

Area = l $\times$ b

= 98$m^2$
