Question

The length and breadth of a rectangle are in the ratio 6 : 5 and its perimeter is 110 m. The area of the rectangle is ___ $c{m}^2$

• A. 750
• B. 650
• C. 700
• D. 800

Answer 1

The correct option is A

750

Let the length and breadth of the rectangle be $6\times$ and $5\times$ respectively

Perimeter = 2 (l + b)

110 = 2(6 x + 5 x)

x = 5

$\therefore$ length (l) = 6(5) = 30 m

breadth (b) = 5(5) = 25 m

Area of rectangle $=l\times b$

$=\left(30\right)\left(25\right)$

$=750m^2$
