Q:

A) 110 | B) 120 |

C) 130 | D) 140 |

Answer & Explanation
Answer: B) 120

Explanation:

Explanation:

let length = x and breadth = y then

2(x+y) = 46 x+y = 23

x²+y² = 17² = 289

now (x+y)² = 23²

x²+y²+2xy= 529

289+ 2xy = 529

xy = 120

area = xy = 120 sq.cm

x(x+5) = 750

x² + 5x - 750= 0

(x+30)(x-25)= 0

x = 25
